Bring back PL011 UART FIFO support to pluart(4). This time with working
tx interrupts.

Special treatment of Server Base System Architecture (SBSA) generic UART
devices is required as presence of the interrupt trigger level register
is not guaranteed. Therefore treat such devices of having a 1-byte FIFO.
