Version 2 of the Server Base System Architecture (SBSA) describes the
Generic UART registers as 32 bits wide. At least one implementation, found
of the Qualcomm Technologies QDF2432, only supports 32 bit accesses. While
other implementations may also support smaller sized accesses, simply use
32 bit accesses all the time for the SBSA UART for simple, broad,
compatibility.
