    drivers/char: pl011: Enable receive timeout interrupt
    
    The commit 874f76a "PL011: fix reverse logic for interrupt mask register"
    introduced regression on the Versatile Express. The board didn't receive
    correctly input.
    
    The timeout interrupt may be asserted when the FIFO is not empty, and no 
futher
    data is received over a 32-bit period.
