cac73f20ac serial: nulldev: Add nulldev serial driver
Some device the serial console's initialization cannot run early during
the boot process. Hence, nulldev serial device is helpful on that
situation.

For example, if the serial module was implemented in FPGA. Serial
initialization is prohibited to run until the FPGA was programmed.

This commit is to adding nulldev serial driver. This will allows the
default console to be specified as a nulldev.

c5f8dd482b serial: Add serial driver for Intel MID
Add a specific serial driver for Intel MID platforms.

It has special fractional divider which can be programmed via UART_PS,
UART_MUL, and UART_DIV registers.

The UART clock is calculated as

	UART clock = XTAL * UART_MUL / UART_DIV

The baudrate is calculated as

	baud rate = UART clock / UART_PS / DLAB

Initialize fractional divider correctly for Intel Edison platform.

For backward compatibility we have to set initial DLAB value to 16
and speed to 115200 baud, where initial frequency is 29491200Hz, and
XTAL frequency is 38.4MHz.

aed2fbef5e dm: serial: Tidy up the pl01x driver
Adjust the driver so that leaf functions take a pointer to the serial port
register base. Put all the global configuration in the init function, and
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.
