Subject: [PATCH v6 2/4] dt-bindings: clock: support i.MX95 BLK CTL module

From: Peng Fan <peng.fan@....com>

i.MX95 includes BLK CTL module in several MIXes, such as VPU_CSR in
VPUMIX, CAMERA_CSR in CAMERAMIX and etc.

The BLK CTL module is used for various settings of a specific MIX, such
as clock, QoS and etc.

This patch is to add some BLK CTL modules that has clock features.
