We should use the algorithm in the Linux kernel so that the UART divisor
calculation is more accurate. It also fixes problems on some picky UARTs
that have sampling anomalies.

unified. After all, the core is the same for all processors, just the
peripheral set differs (which gets handled in the drivers).
