libpayload: ipq808x: introduce uart driver

This adds a UART driver for the ipq8064 controller. It still does not
    quite work in the receive direction - the receive FIFO returns read
    data in 32 bit chunks, which means that 4 keys need to be pressed
    before a character pops out of the driver (and it reports it as a
    single character).

This issue is being addressed separately, the driver is being checked
    in to facilitate concurrent development.
