7b9978883c arch/arm: optimize context switch speed 
The current context save implementation saves registers of each task
to xcp context, which is unnecessary because most of the arm registers are
already saved in the task stack, this commit replace the xcp context with
stack context to improve context switching performance and reduce the tcb
space occupation of tcb instance.

0a8d951837 arch/arm: correct the frame pointer register declare 
In AArch32, the frame pointer is stored in register R11 for ARM code or register R7 for Thumb code.
In AArch64, the frame pointer is stored in register X29.
