Subject: [PATCH v2 1/2] dt-bindings: soc: rockchip: Fix compatibles for
 RK3588 VO{0,1}_GRF

According to RK3588 TRM, VO0_GRF and VO1_GRF have a similar layout, but
definitely not an identical one, therefore sharing the compatible is not
really justified.

Since currently there is no user of this, hence no ABI break, let's fix
it by providing dedicated compatibles while deprecating the old one.
