For arch specific codes, we use arch_xxx() to name the function. So, rename cpu_ticks/cpu_tickrate/set_hw_timeout/init_hw_timer to follow this convention. Then, use arch interface to set timeout value in update_physical_timer(). Furthermore, remove hw_timer.h and move its contents into common/ timer.h.
