* early-8250 requires BASE_BAUD to be defined and includes this header.
* We put in a typical value:
* (core clk / 16) - i.e. UART samples 16 times per sec.
* Athough in multi-platform-image this might not work, specially if the
* clk driving the UART is different.
* We can't use DeviceTree as this is typically for early serial.
