After check the official specification of ARM ISA and Thumb ISA, the arch_setjmp_thumb.S are written by arm unified assembly language, so it easy to make it works for ARM and thumb ISA. Signed-off-by: Huang Qi <huangqi3@xiaomi.com>

Summary
After check the official specification of ARM ISA
and Thumb ISA, the arch_setjmp_thumb.S are written
by arm unified assembly language, so it easy to make it works for ARM and thumb ISA.
Impact
setjmp/longjmp for Cortex A processor
Testing
Tested on sabre-6quad:ostest (both thumb mode and arm mode)
