xtensa: clean up do_interrupt/do_IRQ
- set up irq registers and call irq_enter/irq_exit once for each kernel
entry due to interrupt;
- don't attempt to clear current IRQ in the do_interrupt, IRQ handler
will take care of it;
- find pending interrupt with highest priority before every ISR
invocation.
