Adjust the driver so that leaf functions take a pointer to the serial port

use the same settings from then on.
This makes it much easier to move to driver model without duplicating the
code, since with driver model we use platform data rather than global
settings.
The driver is compiled with either the CONFIG_PL010_SERIAL or
CONFIG_PL011_SERIAL option and this determines the uart type. With driver
model this needs to come in from platform data, so create a new
CONFIG_PL01X_SERIAL config which brings in the driver, and adjust the
driver to support both peripheral variants.
