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.

dm: serial: Allow driver-model serial to be disabled for TPL

Add separate enable/disable controls for driver-model serial. While this
is generally enabled in SPL it may not be in TPL, since serial output can
be obtained with the debug UART with minimal code size.
