This makes it easy to add SMP support for new devices by keying
on a device node for the release sequence. We add the
enable-method property for the cpus property to specify that we
want to use the gcc-msm8660 release sequence (which is going to
look for the global clock controller device node to map some
Scorpion specific power and control registers). We also remove
the nr_cpus detection code as that is done generically in the DT
CPU detection code.

Right now hotplug.c only really implements msm_cpu_die as a wfi. Just
move that implementation into platsmp.c. At the same time we use the
existing wfi() instead of inline asm.

The contents of mach/board.h are only used by files within
mach-msm so there is no need to export this file outside of the
mach-msm directory. Move the contents of the file to common.h to
allow us to compile MSM in the multi-platform kernel.

Nobody is using these mappings so just drop them. of_iomap() in
the timer driver will take care of it for us. Doing this allows
us to remove the 8x60 and 8960 iomap files completely.

Several of the ioremap functions use unsigned long in places
resulting in truncation if physical addresses greater than
4G are passed in. Change the types of the functions and the
callers accordingly.

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:

The timer code relies on #defines from mach/iomap.h, cpu_is_*()
checks, and a global irq #define. All this makes this file
impossible to compile in a mult-target build. Therefore, make a
sys_timer struct for each SoC so that machine descriptors can
reference the correct timer. Then go through and replace all the
defines with raw values that are passed to a common
initialization function.
This paves the way to adding DT support to this code as well as
allows us to compile this file on multiple targets at the same
time.
