[PATCH v4 2/6] dt-bindindgs: clock: nxp: support i.MX95 Camera CSR module

["Peng Fan (OSS)" <peng.fan@oss.nxp.com>]

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

The i.MX95 Camera CSR is a set of registers that provides various
configuration and status of the Camera modules’ operations. Registers
are available to enable clock gating to the ISP and CSI-2 pixel
formatters, enable transport of various pixel data and non-pixel data
types, control their routing, and other functions. Status registers
provide pixel data type error information and pending transaction
from Camera NoC initiators.

This patch is to add clock features for Camera CSR.
