The i.MX Image Processing Unit (IPU) contains a number of image processing
blocks that sit right in the middle between DRM and V4L2. Some of the modules,
such as Display Controller, Processor, and Interface (DC, DP, DI) or CMOS
Sensor Interface (CSI) and their FIFOs could be assigned to either framework,
but others, such as the dma controller (IDMAC) and image converter (IC) can
be used by both.
The IPUv3 core driver provides an internal API to access the modules, to be
used by both DRM and V4L2 IPUv3 drivers.

The former has to be done before disabling the DMFC, the latter has to be
done afterwards. Otherwise the DMFC FIFOs never get cleared properly.

There are only a few users of the DRM_LOG_KMS() macro. We can simplify
the DRM code a bit by replacing them by DRM_DEBUG_KMS().

CRTC offsets are only set with the initial modeset, any
subseqent pageflips assume them to be kept the same, so
we need to remember the current state until another modeset
changes it.

We didn't take the pixel format into account, so x-direction
offsets were off by a factor of 2 or 4 for 16bpp and 32bpp
framebuffers.

Even though we do not enable the hardware double buffering feature
right now, set the second base address pointer (EBA1) as well to
increase robustness.

This patch adds support for a drm overlay plane on DI0 using the DP.
In principle, the overlay plane could also be used on DI1, but to switch
the overlay plane between display interfaces, the base planes would have
to be exchanged transparently while both display interfaces are inactive.
