sifive_uart: Implement interrupt pending register
The watermark bits are set in the interrupt pending register according
to the configuration of txcnt and rxcnt in the txctrl and rxctrl
registers.

Since the UART TX does not implement a FIFO, the txwm bit is set as long
as the TX watermark level is greater than zero.
