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
