_xtensa_context_save. The order of operations has now changed and we
can save A3 with the rest of the 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_disable, use XCHAL_EXCM_LEVEL
For up_irq_save, use XCHAL_IRQ_LEVEL.
Then we can use svcall in enter_crritical_section.
