[U-Boot] [PATCH] serial: sh: Use the clock framework to obtain clock config
Since we now have clock driver on the RCar Gen3 , obtain the clock configuration using the clock framework functions. In case this fails, fall back to the original code for pulling the clock config directly out of OF.

Applied, thanks!
