qinwei1 e77b06721b arch: arm64: ARMv8-A support for NuttX
N/A

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
