ARM: set arch_gettimeoffset directly
remove ARM's struct sys_timer .offset function pointer, and instead
directly set the arch_gettimeoffset function pointer when the timer
driver is initialized. This requires multiplying all function results
by 1000, since the removed arm_gettimeoffset() did this. Also,
s/unsigned long/u32/ just to make the function prototypes exactly
match that of arch_gettimeoffset.
