sched/rt, ARM: Use CONFIG_PREEMPTION

Browse Source 
CONFIG_PREEMPTION is selected by CONFIG_PREEMPT and by CONFIG_PREEMPT_RT.
Both PREEMPT and PREEMPT_RT require the same functionality which today
depends on CONFIG_PREEMPT.

Switch the entry code, cache over to use CONFIG_PREEMPTION and add output
in show_stack() for PREEMPT_RT.
