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.

Add a register lookup table, which allows the register offsets to be
adjusted on a per-port basis.

Prepare for REG_* register accessors. This change involves introducing
pl011_reg_to_offset() to convert REG_* to the hardware register offset,
and converting all call sites to use REG_* names. We need to fix up
locations where we check for equivalence of register offsets as well.
Much of this change was made via these sed expressions:
s/ST_UART01[1x]\(_[^_]*\|_LCRH_[TR]X\)\>/REG_ST\1/
s/UART01[1x]_\(DR\|RSR\|ECR\|FR\|ILPR\|[IF]BRD\|LCRH\|CR\|IFLS\|IMSC\|RIS\|MIS\|ICR\|DMACR\)\>/REG_\1/g
