DT kernel on da850-evm comes up with garbled UART logs. This is because
of mismatch in actual module clock rate and rate specified(clock-frequency)
in DT blob. kernel should not assume or depend on bootloaders clock
configuration, instead let it find the clock rate at runtime.

Issue discussed here before arriving on this implementation:
"ARM: davinci: da850 evm: update clock rate for UART 1/2 DT nodes"
