[v3,0/4] Add link frequency to bitmap helper

Message

Hi folks,

This set adds a little helper for sensor drivers to match link frequencies
from system firmware with those supported the driver and generate a bitmap
suitable for passing to the control framework.

Imx319, imx334 and imx355 drivers are converted to use the helper, too.

I've tested imx319 and imx355 drivers.

since v2:

- Also fix EXPORT_SYMBOL_GPL() macro argument.

since v1:

- Call the helper v4l2_link_freq_to_bitmap, it's nicer to use that way and
  aligns with v4l2_get_link_freq, too.

- Fix kerneldoc issues and compiler warnings.

  media: imx334: Use v4l2_link_freq_to_bitmap helper
  media: imx319: Use v4l2_link_freq_to_bitmap helper
  media: imx355: Use v4l2_link_freq_to_bitmap helper
