drivers/uart: Use uart_platform_refclk for all UART models
Allow the platform to override the input clock for the UART by
implementing the routine uart_platform_refclk and setting the Kconfig
value UART_OVERRIDE_REFCLK. Provide a default uart_platform_refclk
routine which is disabled when UART_OVERRIDE_REFCLK is selected. This
works around ROMCC not supporting weak routines.
Testing on Galileo:
* Edit the src/mainboard/intel/galileo/Makefile.inc file:
* Add "select ADD_FSP_PDAT_FILE"
* Add "select ADD_FSP_RAW_BIN"
* Add "select ADD_RMU_FILE"
* Place the FSP.bin file in the location specified by CONFIG_FSP_FILE
* Place the pdat.bin files in the location specified by
CONFIG_FSP_PDAT_FILE
* Place the rmu.bin file in the location specified by CONFIG_RMU_FILE
* Build EDK2 CorebootPayloadPkg/CorebootPayloadPkgIa32.dsc to generate
UEFIPAYLOAD.fd
* Testing is successful when CorebootPayloadPkg is able to properly
initialize the serial port without using built-in values.
