leon, apbuart: added register defines: FIFO, delay int
The FIFOs available capability bit is available in the UART Control Register:
FIFOs available (FA) - Set to 1 when receiver and transmitter FIFOs are
available. When 0, only holding register is available.
Delay interrupt can delay a receive character interrupt to better handle RX bursts.
