Generalize ns16550 driver to work with more chips.

Some UART controllers are compatible with 16550A, but have more spacing
between registers. In particular, ARMADA 385, which is the basis of
Turris Omnia router, has a compatible UART with 32b registers instead of 8b
(with the top three bytes unused).

Note: The device tree file hints that some UARTs may need register reads/writes
that are wider than 8 bits, and this commit does not address that possibility.
