zhuyanlin 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.
