fbc1da98b7 xtensa: use swint to swith context
Reason for use sw-interrupt as syscall interrupt:
The xtensa `syscall` instruction can cause SYSCALL interrupt.
But SYSCALL interrupt is same interrupt level with level-one
interrupt.
Nuttx swint can enter `enter_critical_section` and gerenate
interrupt.

For up_irq_save,  use XCHAL_IRQ_LEVEL.
Then we can use svcall in enter_crritical_section.

f826e053ae arch/xtensa/esp32: Remove the QEMU special case when initializing the
heap.

QEMU had a different ROM image that used the regions of PRO CPU for both
CPUs.  This was causing crashes when running SMP mode as the heap was
being corrupted when the APP CPU starts.

QEMU is now loading the same image as the hardware chip and thus this
special case doesn't exist anymore.
