[ Upstream commit 22b2cfad752d4b278ea7c38c0ee961ca50198ce8 ]

RGB32 and BGR32 formats were inadvertently removed from the switch
statement in ipu_pixelformat_to_colorspace(). Restore them.

Support is already implemented for the corresponding DRM formats,
just hook up the remaining V4L2 pixel formats.

The CSI offsets are wrong for both CSI0 and CSI1. They are at

drm/imx: ipu-v3 plane offset and IPU id fixes

- Fix U/V plane offsets for odd vertical offsets. Due to wrong operator
  order, the y offset was not rounded down properly for vertically
  chroma subsampled planar formats.
- Fix IPU id number for boards that don't have an OF alias for their
  single IPU in the device tree. This is necessary to support imx-media
  on i.MX51 and i.MX53 SoCs.

This is better than storing -ENODEV in the id number. This fixes SoCs
with only one IPU that don't specify an IPU alias in the device tree.

Don't populate the const read-only arrays int_reg on the stack but instead
make them static. Makes the object code smaller by over 80 bytes:

The IDMAC_LOCK_EN registers on i.MX51 have a different layout, and on
i.MX53 enabling the lock feature causes bursts to get lost. Restrict
enabling the burst lock feature to i.MX6.
