libpayload: Remove redundant 8250 MMIO32 UART driver

The more generic 8250 driver can handle both port-mapped and memory-
    mapped 8250-compatible UARTs, with different register sizes. Thus, a
    separate driver for MMIO32 is not needed.
    The generic 8250 driver was tested to work for both output and input,
    on Apollolake SoC, which only presents an MMIO32 UART.
