MIPS: alchemy: Remove pointless irqdisable/enable
bcsr_csc_handler() is a cascading interrupt handler. It has a
disable_irq_nosync()/enable_irq() pair around the generic_handle_irq()
call. The value of this disable/enable is zero because its a complete
noop:
disable_irq_nosync() merily increments the disable count without
actually masking the interrupt. enable_irq() soleley decrements the
disable count without touching the interrupt chip. The interrupt
cannot arrive again because the complete call chain runs with
interrupts disabled.
Remove it.
[ralf@linux-mips.org: Fold in followup fix from Thomas Gleixner.]
