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.

Sush do not generate interrupt when up_irq_save.
Software int can generate interrupt when up_irq_save.
