Subject: [PATCH v2 0/3] media: i2c: gc2145: GC2145 sensor support

This serie adds support for the GalaxyCore GC2145 sensor.
Initialization is based on scripts provided by GalaxyCore,
allowing 3 fixed configurations supported for the time being.

Minimum controls have been added in order to allow it to
be successfully used with libcamera and dcmipp driver (under
review) on STM32MP13 platform.

The sensor also supports Bayer formats however I removed
them for the time being since they would require more
controls to be exposed.  They will be added again later on.

v2: - split vendor-prefixes update into a separate commit
    - correction into dt-bindings (description, const i2c address,
      lowcase of supplies, node naming
    - correct KConfig (avoid VIDEO_V4L2_SUBDEV_API, V4L2_FWNODE and add
      V4L2_CCI_I2C)
    - usage of v4l2-cci framework for accessing to device registers
    - correction in power-on / power-off sequences and update
      usleep_range delay
    - detail MIPI configuration and stop register access to stop
      streaming
    - removal of SYSTEM_SLEEP_PM_OPS (and streaming variable)
    - various small fixes, typo, oneline functions
    - removal of useless HBLANK control considereing that RAW isn't
      supported for the time being
    - removal of RAW parts
    - usage of dev_err_probe
