[PATCH v2 4/4] arm64: dts: rockchip: rk356x: add LVDS node

[Rok Markovic <rok@kanardia.eu>]

This commit adds the LVDS transmitter node for the RK356x SoC, assigning
its D-PHY, GRF handle and power domain. The block has no register block
and no clock of its own. It is left disabled by default, to be enabled
by specific board files.

Signed-off-by: Rok Markovic <rok@kanardia.eu>
Assisted-by: Claude:claude-opus-4-8

Changes in v2:
  - Drop the clock from the LVDS node; the block takes none.
