Eliminate the sharing of IRQ names among the differenct Alchemy

This patch also renames the GPIO irq number constants. It's really

Code which relied on certain irq numbers to have the same name
across all supported cpu subtypes is changed to determine current

a "compat" symbol is used.

DBDMA descriptors need to be located at 32-byte aligned addresses;
however kmalloc in conjunction with the SLAB allocator and
CONFIG_DEBUG_SLUB enabled doesn't deliver any. The dbdma code works
around that by allocating a larger area and realigning the start
address within it.
When freeing a channel however this adjustment is not taken into
account which results in an oops:
Kernel bug detected[#1]:

Fix this by recording the address delivered by kmalloc() and using
it as parameter to kfree().
This fix is only necessary with the SLAB allocator and CONFIG_DEBUG_SLAB
enabled; non-debug SLAB, SLUB do return nicely aligned addresses,
debug-enabled SLUB currently panics early in the boot process.

The handle_edge_irq() flowhandler disables edge int sources which occur
too fast (i.e. another edge comes in before the irq handler function
had a chance to finish). Currently, the mask_ack() callback does not
ack the edges in hardware, leading to an endless loop in the flowhandler
where it tries to shut up the irq source.
When I rewrote the alchemy IRQ code I wrongly assumed the mask_ack()
callback was only used by the level flowhandler, hence it omitted the
(at the time pointless) edge acks. Turned out I was wrong; so here
is a complete mask_ack implementation for Alchemy IC, which fixes
the above mentioned problem.

(Thanks to Al Viro for reminding me of this, via Ingo)
CPU_MASK_ALL is the (deprecated) "all bits set" cpumask, defined as so:
#define CPU_MASK_ALL (cpumask_t) { { ... } }
Taking the address of such a temporary is questionable at best,
unfortunately 321a8e9d (cpumask: add CPU_MASK_ALL_PTR macro) added
CPU_MASK_ALL_PTR:
#define CPU_MASK_ALL_PTR (&CPU_MASK_ALL)
Which formalizes this practice. One day gcc could bite us over this
usage (though we seem to have gotten away with it so far).
So replace everywhere which used &CPU_MASK_ALL or CPU_MASK_ALL_PTR
with the modern "cpu_all_mask" (a real struct cpumask *), and remove
CPU_MASK_ALL_PTR altogether.

The current in-kernel Alchemy GPIO support is far too inflexible for
all my use cases. To address this, the following changes are made:
* create generic functions which deal with manipulating the on-chip
GPIO1/2 blocks. Such functions are universally useful.
* Macros for GPIO2 shared interrupt management and block control.
* support for both built-in CONFIG_GPIOLIB and fast, inlined GPIO macros.
If CONFIG_GPIOLIB is not enabled, provide linux gpio framework
compatibility by directly inlining the GPIO1/2 functions. GPIO access
is limited to on-chip ones and they can be accessed as documented in
the datasheets (GPIO0-31 and 200-215).
If CONFIG_GPIOLIB is selected, two (2) gpio_chip-s, one for GPIO1 and
one for GPIO2, are registered. GPIOs can still be accessed by using
the numberspace established in the databooks.
However this is not yet flexible enough for my uses: My Alchemy
systems have a documented "external" gpio interface (fixed, different
numberspace) and can support a variety of baseboards, some of which
are equipped with I2C gpio expanders. I want to be able to provide
the default 16 GPIOs of the CPU board numbered as 0..15 and also
support gpio expanders, if present, starting as gpio16.
To achieve this, a new Kconfig symbol for Alchemy is introduced,
CONFIG_ALCHEMY_GPIO_INDIRECT, which boards can enable to signal
that they don't want the Alchemy numberspace exposed to the outside
world, but instead want to provide their own. Boards are now respon-
sible for providing the linux gpio interface glue code (either in a
custom gpio.h header (in board include directory) or with gpio_chips).
To make the board-specific inlined gpio functions work, the MIPS
Makefile must be changed so that the mach-au1x00/gpio.h header is
included _after_ the board headers, by moving the inclusion of
the mach-au1x00/ to the end of the header list.
See arch/mips/include/asm/mach-au1x00/gpio.h for more info.

Replace the current sysctl-based suspend interface with a new sysfs-
based one which also uses the Linux-2.6 suspend model.
To configure wakeup sources, a subtree for the demoboards is created
under /sys/power/db1x:
sys/
`-- power
`-- db1x
|-- gpio0
|-- gpio1
|-- gpio2
|-- gpio3
|-- gpio4
|-- gpio5
|-- gpio6
|-- gpio7
|-- timer
|-- timer_timeout
|-- wakemsk
`-- wakesrc
The nodes 'gpio[0-7]' and 'timer' configure the GPIO0..7 and M2
bits of the SYS_WAKEMSK (wakeup source enable) register. Writing '1'
enables a wakesource, 0 disables it.
The 'timer_timeout' node holds the timeout in seconds after which the
TOYMATCH2 event should wake the system.
The 'wakesrc' node holds the SYS_WAKESRC register after wakeup (in hex),
the 'wakemsk' node can be used to get/set the wakeup mask directly.
For example, to have the timer wake the system after 10 seconds of sleep,
the following must be done in userspace:
echo 10 > /sys/power/db1x/timer_timeout
echo 1 > /sys/power/db1x/timer
echo mem > /sys/power/sleep
