2d016f8d21 arch: xtensa: Fix the PS register handling
Summary:
- I noticed that DEBUGASSERT sometimes happens in nxsem_wait()
  when testing Wi-Fi with esp32-devkitc:wsifi_smp
- The call stack was not from an interrupt handler and actually
  g_current_regs[] were correct, even though asserted with
  (up_interrupt_handler() == false)
- Finally, I found that we need to call rsync after we set
  a new value to the PS register which is described in the
  Xtensa document.
- This commit fixes this issue

Impact:
- All xtensa architectures

Testing:
- Tested with esp32-devkitc:wifi_smp and esp32-devkitc:wifi
