b10c8955cf arch/Kconfig: Don't depend on Xtensa for the SUPPRESS_CLOCK_CONFIG
option.  This config was probably added in the early bring up of the
ESP32 chip. At that point the clock config was suppressed and we relied
on the bootloader.  Now we can configure the clock from NuttX.

The option itself is still useful and can be used for any other
architecture or chip.

7b9978883c arch/arm: optimize context switch speed
The current context save implementation saves registers of each task
to xcp context, which is unnecessary because most of the arm registers are
already saved in the task stack, this commit replace the xcp context with
stack context to improve context switching performance and reduce the tcb
space occupation of tcb instance.

6fa4a42e34 xtensa/: Save A3 as part of the regular context saving.
It was separate because the syscal handler was using it before calling

can save A3 with the rest of the context.
