As we augmented the regulator core to accept a GPIO descriptor instead
of a GPIO number, we can augment the fixed GPIO regulator to look up
and pass that descriptor directly from device tree or board GPIO
descriptor look up tables.
Some boards just auto-enumerate their fixed regulator platform devices
and I have assumed they get names like "fixed-regulator.0" but it's
pretty hard to guess this. I need some testing from board maintainers to
be sure. Other boards are straight forward, using just plain
"fixed-regulator" (ID -1) or "fixed-regulator.1" hammering down the
device ID.
It seems the da9055 and da9211 has never got around to actually passing
any enable gpio into its platform data (not the in-tree code anyway) so we
can just decide to simply pass a descriptor instead.
The fixed GPIO-controlled regulator in mach-pxa/ezx.c was confusingly named
"*_dummy_supply_device" while it is a very real device backed by a GPIO
line. There is nothing dummy about it at all, so I renamed it with the
infix *_regulator_* as part of this patch set.

The mach/*.h headers are now inaccessible to any external code,
so we can move them all into the mach-mmp directory itself
and remove the subdirectories.
A few headers are not used at all, so we remove them here.

Since PXA_GPIO_TO_IRQ() & MMP_GPIO_TO_IRQ() macro are depended on
arch code, move them from gpio driver to platform driver instead.

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:

MMP2 have the internal sram, this sram can be allocated
for video, power management and secure processor.
Now the sram usage is:
0xd1000000 ~ 0xd101ffff (128KB) : reserved for secure processor
0xd1020000 ~ 0xd1037fff (96KB) : for video and PM
Register the internal sram's second half 96KB buffer,
so that video and PM can dynamically alloc/free from it.
