This does not make sense as this register only has one bit to control.
Why do we even need to change this, can you please explain what happens 
if we do not change this?

These two registers should have default value of 0x06 as this has only 
one clk selection field with bits 2:1.

In that case you should probably consider using regmap_register_patch() 
for corrections to the default registers in sm8250 case.

As regmap_register_patch() not working in this use case, updating 
defaults in probe for sc7280 specific differences.

In what way is regmap_register_patch() not working?
