Russell King e4df9a8053 tty: amba-pl011: clean up LCR register offsets
As we can detect when the LCR register is split between TX and RX,
we don't need three entries in the table to deal with this.  Reduce
this down to two entries by converting the REG_ST_LCRH_* entries to
standard REG_LCRH_* and remove REG_LCRH.
