Andy Shevchenko c42850f1ae serial: 8250_mid: recognize interrupt source in handler 
There is a special register that shows interrupt status by source. In
particular case the source can be a combination of DMA Tx, DMA Rx, and UART.

Read the register and call the handlers only for sources that request an
interrupt.

Fixes: 6ede6dcd87 ("serial: 8250_mid: add support for DMA engine handling from UART MMIO")
