This change adds a Qualcomm GENI SE QUP device driver as a wrapper for
actually enabled and used serial devices found on a board.
At the moment the driver is pretty simple, its intention is to populate
childred devices and provide I/O mem read interface to them as clients,
this is needed for GENI UART driver to set up a proper clock divider
and provide the actually asked baud rate.
