Subject: [PATCH v3 2/7] dt-bindings: phy: rockchip-inno-csi-dphy: make
 power-domains non-required

From: Michael Riesch <michael.riesch@...labora.com>

There are variants of the Rockchip Innosilicon CSI DPHY (e.g., the RK3568
variant) that are powered on by default as they are part of the ALIVE power
domain.
Remove 'power-domains' from the required properties in order to avoid false
negatives.

Fixes: 22c8e0a69b7f ("dt-bindings: phy: add compatible for rk356x to rockchip-inno-csi-dphy")
