On rk3399 the GRF isn't used for pll lock status. It's used for PLL muxes. technically if you don't include it then the PLL muxes won't be
changeable. Hopefully the code handles this if the property is listed
as "Optional". ...and unless Heiko says otherwise, you probably need
to list it as "Optional" since (presumably) there might be backward
compatibility issues.
