Peter Mitsis 5c39418ae8 k20uart: Fix check for Rx/Tx irq 
Due to a quirk of the k20 UART, when checking if either a Tx or Rx
irq is ready, one must first check whether the UART has enabled the
Tx and/or Rx interrupts.  If this is not done, then all one is doing
is testing the UART to determine if it is ready to Tx and/or Rx.
