After converting the PXA driver to use GPIO descriptors for
card detect and write protect it is relatively simple to
convert it to also use a descriptor for getting the optional
power control GPIO.
The polarity inversion flag can also go away from the platform
data since this is indicated in the GPIO machine descriptor
table.

This deletes the platform data passed for card detect and
write protect from various PXA machines.
Make sure to keep .gpio_card_ro_invert as this is still in
use by some machines and needed to set the right flag to
the MMC core (will be cleaned up later).

This adds GPIO descriptor look-up tables for a whole bunch
of PXA boards with MMC card detect (CD) and write protect (WP)
GPIO lines, so we can move away from the hard-coded GPIO
numberspace.
In some cases the platforms were compulsively including the
<linux/gpio.h> header even if they weren't actually using
it, and in these cases I simply replaced that inclusion with
the more appropriate <linux/gpio/machine.h> which is what
board files should be including most of the time.

Since dm9000 driver added support for a vcc regulator, platform data
based platforms have their ethernet broken, as the regulator claiming
returns -EPROBE_DEFER and prevents dm9000 loading.
This patch fixes this for all pxa boards using dm9000, by using the
specific regulator_has_full_constraints() function.
This was discovered and tested on the cm-x300 board.
Fixes: 7994fe55a4 ("dm9000: Add regulator and reset support to dm9000")

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:

This patch moves the platform data definition from
arch/arm/plat-pxa/include/plat/i2c.h to include/linux/i2c/pxa-i2c.h so
it can be accessed from x86 the same way as on ARM.
This change should make no functional change to the PXA code. The move
is verified by building the following defconfigs:
cm_x2xx_defconfig corgi_defconfig em_x270_defconfig ezx_defconfig
imote2_defconfig pxa3xx_defconfig spitz_defconfig zeus_defconfig
