Move register and other definitions out of the
include/asm-arm/arch-s3c2410 into the the arch
directories of include/asm-arm/plat-s3c24xx and
include/asm-arm/plat-s3c.
This move is in preperation of the merging of
s3c2400 and s3c6400.

These patches add full SSP/MCU support for the HP Jornada 720
machine. Its needed to handle keyboard, touchscreen, battery
and backlight/lcd.
The main driver exports functions and the header file exports
the command values. When talking to the MCU the general procedure
is to start MCU, send command (using ssp_inout(command)), the
proper reply is always TXDUMMY. After receiving TXDUMMY you can
send the value you wish pushed (for example brightness level).
End with ssp_end() so the spinlock gets unlocked.
Drivers using this havent been implemented yet, but will shortly.

1. split pxa_cpu_suspend to pxa25x_cpu_suspend and pxa27x_cpu_suspend
and make pxa25x_cpu_pm_enter() and pxa27x_cpu_pm_enter() to invoke
the corresponding _suspend functions, thus remove all those ugly
#ifdef .. #endif out of sleep.S
2. move the declarations of those suspend functions to pm.h
note: this is not a clean enough solution until all the pxa25x and
pxa27x specific part is further removed out of sleep.S, sleep.S is
supposed to contain generic code only

1. introduce a structure pxa_cpu_pm_fns for pxa25x/pxa27x specific
operations as follows:
struct pxa_cpu_pm_fns {
int save_size;
void (*save)(unsigned long *);
void (*restore)(unsigned long *);
int (*valid)(suspend_state_t state);
void (*enter)(suspend_state_t state);
}
2. processor specific registers saving and restoring are performed
by calling the corresponding (*save) and (*restore)
3. pxa_cpu_pm_fns->save_size should be initialized to the required
size for processor specific registers saving, the allocated
memory address will be passed to (*save) and (*restore)
memory allocation happens early in pxa_pm_init(), and save_size
should be assigned prior to this (which is usually true, since
pxa_pm_init() happens in device_initcall()
4. there're some redundancies for those SLEEP_SAVE_XXX and related
macros, will be fixed later, one way possible is for the system
devices to handle the specific registers saving and restoring

Moreover the numbering is changed to be zero indexed as this is more
