But it was forgotten to remove grf check when deciding between the pll rate ops (read-only vs. read-write), so a clock driver without the needed grf reference might've been put into the read-only mode just because the grf reference was missing. This affected the rk356x that needs to reclock certain plls at boot. Fix this by removing the check for the grf for selecting the utilized operations.
