drivers: media: camera: Add sync op support

Add sync file op support in VI driver.
Sub devices will be synchronized when the MFI interrupt
arrives to VI driver. At present this interrupt is
configured when the ROI of focus area ends during the
current frame capture.

Fix vi2 and vi4 differences using fops in addition to
the original commit.
Cleanup MFI code in the active isr flow.
