Without CONFIG_SPARSE_IRQ, we rely on mach/irqs.h to define NR_IRQS
globally. Do the minimal conversion by setting .nr_irqs in each
machine descriptor.
Only the vision_ep9307 machine has extra IRQs for GPIOs, so make
.nr_irqs the original value there, while using the plain NR_EP93XX_IRQS
everywhere else.

The MaverickCrunch support for ep93xx never made it into glibc and
was removed from gcc in its 4.8 release in 2012. It is now one of
the last parts of arch/arm/ that fails to build with the clang
integrated assembler, which is unlikely to ever want to support it.
The two alternatives are to force the use of binutils/gas when
building the crunch support, or to remove it entirely.
According to Hartley Sweeten:
"Martin Guy did a lot of work trying to get the maverick crunch working
but I was never able to successfully use it for anything. It "kind"
of works but depending on the EP93xx silicon revision there are still
a number of hardware bugs that either give imprecise or garbage results.
I have no problem with removing the kernel support for the maverick
crunch."
Unless someone else comes up with a good reason to keep it around,
remove it now. This touches mostly the ep93xx platform, but removes
a bit of code from ARM common ptrace and signal frame handling as well.
If there are remaining users of MaverickCrunch, they can use LTS
kernels for at least another five years before kernel support ends.

Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.
This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:

A number of the peripherals for the ep93xx are registered at
startup using platform_data that is passed from the board init
code to the core code. This data is then copied to a local
static variable in the core code. Since the data is copied,
the original data can be marked as __initdata and discarded
after startup is complete.
This adds the __initdata tag to all the appropriate data in
the various ep93xx board init's. Specifically, all the
struct ep93xx_eth_data, struct ep93xxfb_mach_info, and
struct i2c_gpio_platform_data.
Also, document the various registration functions and note
what data should be marked as __initdata.
While here, also cleanup a couple over zealous whitespace tabs.
