The RPi3 typically uses the regular UART for high-speed communication with
the Bluetooth device, leaving us the mini UART to use for the serial
console. Add support for this UART so we can use it.

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.

This driver is enabled only for UniPhier SoCs and ARCH_UNIPHIER now
selects OF_CONTROL and SPL_OF_CONTROL.
This driver no longer needs to support platform data configuration.

This adds driver model support with this driver. This was tested by Koelsch
board and Gose board.

This commit converts UniPhier on-chip serial driver to driver model.
Since UniPhier SoCs do not have Device Tree support, some board files
should be added under arch/arm/cpu/armv7/uniphier/ph1-*/ directories.
(Device Tree support for UniPhier platform is still under way.)
Now the base address and master clock frequency are passed from
platform data, so CONFIG_SYS_UNIPHIER_SERIAL_BASE* and
CONFIG_SYS_UNIPHIER_UART_CLK should be removed.
Tested on UniPhier PH1-LD4 ref board.

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
