[PATCH v2 0/3] media: i2c: ov9282: Modernize driver with CCI and streams API

[Xiaolei Wang <xiaolei.wang@windriver.com>]

This series modernizes the ov9282 driver by:

1. Converting to the common CCI (Camera Control Interface) register
   access helpers, which simplifies the code by removing custom I2C
   register access functions.

2. Switching to use the V4L2 sub-device state lock instead of a
   private mutex, improving integration with the V4L2 framework.

3. Migrating from the legacy s_stream callback to the modern
   enable_streams/disable_streams callbacks, providing better support
   for multiplexed streams.

These changes reduce code complexity, improve maintainability, and
align the driver with current V4L2 best practices.

I verified each patch on the Raspberry Pi 5 platform.

Changes in V2:
  - Patch 1: Fixed group hold release error handling in
    ov9282_update_exp_gain()
  - Patch 2: Fixed runtime PM cleanup in probe error path
  - Patch 3: Improved error handling with clearer err_pm_put: label
