serial: mxc: enable the RX pipeline
on imx8(mm) the RXDMUXSEL needs to be set for data going over the wire
(as observable on a connected 'scope) to actually make it into the
RXFIFO
the reference manual is not overly clear about this, and only
mentiones that "UCR3_RXDMUXSEL should always be set." - and since the
CR3 register reverts to its reset values after setting the baudrate,
setting this bit is done during '_mxc_serial_setbgr'
