[BUG] <zynq-mpsoc was broken by #15437 >

[zouboan]

Today, I pulled and synchronized the latest NuttX, but after successfully compiling it, I found that it failed to run. Through the process of bisecting, the issue was ultimately pinpointed to Pull Request #15437
These are the outcomes of my tests on the ZCU111 board regarding the jtag and nsh configurations:

Description / Steps to reproduce the issue

The pull request #15437 changes ARM64_CONTEXT_REGS from 36 to 37, resulting in the stack no longer being 16-byte aligned, which appears to violate the ARMv8-A architecture's requirement for 16-byte stack alignment.
