Since there is slight difference in AMD RV based soc in misc
clk architecture. The fmw property will help in differentiating
the SoCs.

Hi,

This series of patch does the following:
1. Changes the name of the AMD SoC general purpose clk
from ST(a version of SoC) to FCH (name of the IP).
2. Then make the drivers support both older and newer versions of
SoC.

Thanks,
Akshu
