[v3,4/5] media: i2c: alvium: store frame interval in subdev state
Commit Message
Use the newly added storage for frame interval in the subdev state to
simplify the driver.

Changes Since v1:
- Removed FIXME comment and active state check into alvium_s_frame_interval
as suggested by LPinchart.
- Fixed call alvium_set_frame_rate() only for active state into alvium_s_frame_interval
as suggested by LPinchart.
Changes Since v2:
- Collected tag from LPinchart
