Jayachandran C. cbee50f1df Fix interrupt clear in pl011 uart receive function
Clear the interrupt state before reading the input char from the
input FIFO. In the current code there is a window between the read
to the data register and the write to the the ICR, during which an
input char will not cause an interrupt.

This fixes the issue by which the serial port input on QEMU freezes
when using the emulated pl011 serial port.
