Two new options:
CONFIG_PL011_SERIAL_RLCR
Some vendor versions of PL011 serial ports (e.g. ST-Ericsson U8500)
have separate receive and transmit line control registers. Set
this variable to initialize the extra register.
CONFIG_PL011_SERIAL_FLUSH_ON_INIT
On some platforms (e.g. U8500) U-Boot is loaded by a second stage
boot loader that has already initialized the UART. Define this
variable to flush the UART at init time.

Use C structs for registers, and use readl/writel instead of custom
accessors.

The pl01x serial driver was lacking the code to switch baudrates from the
command line. Fixed by simply saving the new baudrate and calling
serial_init() again. Also fixed CamelCase variables, I/O accessors and
comment style.

They only differ in the init function.
This also adds the missing watchdog support for the PL011.
