Subject: [PATCH v3 0/6] media: imx335: 2/4 lane ops and improvements

Another batch of improvements of the imx335 driver.

Patch 1/6 adds support for 2 or 4 lane operation modes.

Patch 2/6 call the V4L2 fwnode device parser to handle controls that are
standardised by the framework.

Patch 3/6 introduces the use of CCI for registers access.

Patch 4/5 uses decimal values for sizes registers (instead of
hexadecimal). This improves overall readability

Patch 5/6 fixes the height value discrepency. Accessible height is 1944,
as per the data sheet in all-pixel scan mode.

Patch 6/6 fixes the max analogue gain value.

changes in v3:
- fix patch 2/6 where we need to free ctrl handler
  on error path.

changes in v2:
- New patch 4/6
- Drop calculating the pixel clock from link freq.
- CCI register address sort (incremental)
- Fix cci_write for REG_HOLD handling and add a comment.
- Remove  unused macros as part of 3/6
