Merge tag 'v6.20-rockchip-drivers1' of https://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into soc/drivers

Two fixes for the default-settings code for the General-Register-Files,
which sets system defaults for some settings like disabling the automatic
jtag/sdmmc switching.

One is a corrected register-offset and the other makes the code actually
look for all matched GRF instances, which it didn't do before.
