Summary:
- Since the stack coloration is done for every 32bits
this function should be done in the same way.
Impact:
- None
Testing:
- Tested with qemu-a53:nsh

Summary:
Arm64 support for NuttX, Features supported:
1. Cortex-a53 single core and SMP support: it's can run into nsh shell at
qemu virt machine.
2. qemu-a53 board configuration support: it's only for evaluate propose
3. FPU support for armv8-a: FPU context switching at NEON/floating-point
TRAP is supported.
4. psci interface, armv8 cache operation(data cache) and smccc support.
5. fix mass code style issue, thank for @xiaoxiang781216, @hartmannathan @pkarashchenko
Please refer to boards/arm64/qemu/qemu-a53/README.txt for detail
Note:
1. GCC MACOS issue
The GCC 11.2 toolchain for MACOS may get crash while compiling
float operation function, the following link describe the issue
and give analyse at the issue:
https://bugs.linaro.org/show_bug.cgi?id=5825
it's seem GCC give a wrong instruction at certain machine which
without architecture features
the new toolchain is not available still, so just disable the MACOS
cibuild check at present
