serial: pl01x: Add support for devices with the rate pre-configured.

For Raspberry Pi, we had the input clock rate to the pl011 fixed in
the rpi.c file, but it may be changed by firmware due to user changes
to config.txt. Since the firmware always sets up the uart (default
115200 output unless the user changes it), we can just skip our own
uart init to simplify the boot process and more reliably get serial
output.

dm: move platform data headers to include/dm/platform_data

The platform_data definitions are generally referenced from both
drivers and board files. That is why header files defining
platform_data sturectures are placed in "include" directory,
but our top level "include" directory is already too cluttered.

Let's collect platform_data definitions under the directory
"include/dm/platform_data" like Linux gathers ones around under
"include/linux/platform_data".

This commit moves two header files:

include/serial_mxc.h -> include/dm/platform_data/serial_mxc.h
include/serial_pl01x.h -> include/dm/platform_data/serial_pl01x.h
