Michael Riesch ff42b17d39 phy: rockchip: phy-rockchip-inno-csidphy: allow writes to grf register 0
[ Upstream commit 8c7c19466c ]

The driver for the Rockchip MIPI CSI-2 DPHY uses GRF register offset
value 0 to sort out undefined registers. However, the RK3588 CSIDPHY GRF
this offset is perfectly fine (in fact, register 0 is the only one in
this register file).
Introduce a boolean variable to indicate valid registers and allow writes
to register 0.
