Subject: [PATCH] ARM: PL011: Ensure IRQs are disabled in UART interrupt
 handler

As the DMA support introduces a separate interrupt-time callback, our
interrupt handler will not be the only handler which takes the port
lock, so we need to ensure that IRQs are disabled.  We must use the
_irqsave variant so we don't inadvertently enable interrupts.
