Add a v4l2 subdevice driver for the Omnivision OV2735 sensor.

The Omnivision OV2735 is a 1/2.7-Inch CMOS image sensor with an
active array size of 1920 x 1080.

The following features are supported:
- Manual exposure an gain control support.
- vblank/hblank control support.
- Test pattern support control.
- Supported resolution: 1920 x 1080 @ 30fps (SGRBG10).

The driver is tested on mainline branch v6.14-rc6 on IMX8MP Debix Model a.

v3 -> v4

In Patch 1/2:
- Removed the clock-names property from the device tree binding.
- Added link-frequencies property to the port node.
- Cleaned up the example by removing unnecessary entries.

In Patch 2/2:
- Removed the cci_ prefix from read/write functions and custom page macros.
- Corrected error handling in the ov2735_page_access() function.
- Calculated PLL parameters dynamically based on the specified link frequency.
- Set resolution registers from format and crop instead of hardcoding.
- Fixed a memory leak in ov2735_parse_endpoint().
- Switched to devm_pm_runtime_*() functions for runtime PM handling.
- Added documentation for the use of msleep() in the power_on() function.
- Corrected GPIO polarity handling in the power_off() function.

v2 -> v3

In Patch 1/2:
- Renamed pwdn pin to enable pin.
- Changed supply names to lowercase and added them to required properties.

In Patch 2/2:
- Stored page number in CCI private bits.
- Added helper functions to handle page switching in cci_read() and cci_write().
- Removed ov2735_mbus_codes.
- Corrected control count to 9.

v1 -> v2

- Added necessary header files.
- Corrected indentation.
- Used the ret parameter in cci_write and cci_read functions.
