The 16bpp BGR order pixel formats 'DRM_FORMAT_ABGR1555' and
'DRM_FORMAT_XBGR1555' also require to be re-ordered to RGB
order for display, just like the format 'DRM_FORMAT_BGR565'
does.

According to LCDIF specification, the input pixel data
width and the output pixel data width can be different,
and this conversion is done by LCDIF automatically. So
config the output data width according to the requested
bus format from the encoder, instead to be same with the
input pixel data width.

According to the LCDIF specification, the Legacy Mode does not
support cropping function in the horizontal direction, so add
Pigeon Mode which can support this kind of function. And when
enable this mode, the legacy horizontal timings configuration
should use stride value but not the active width, and related
pigeon configuration should use the active width but not the
stride value.

Change the 'rpm_suspended' field to be an atomic type from
boolean type to make it have the counting ability which can
help to detect and avoid runtime suspend and resume calls
mismatch caused problems.

After the DISPMIX power domain enabled, all the related registers
will drop their values once runtime pm suspend called. So in the
pm runtime resume process, the LCDIF de-reset and some init jobs
need to be done, and these jobs are no longer necessary to be done
during probe stage anymore.

Add an function to get the LCDIF controller supported bus
formats according to the pixel format bpp. And change the
bus format sanity check in the plane's atomic check to see
if the bus format required by the peripheral attached to
LCDIF can be supported by LCDIF.

This is a new DRM/KMS driver for LCDIF which conforms
to the IMX DRM Core framework. It provides support for
CRTCs, Planes and mode config of KMS.

The LCDIF core driver is responsible to provide controller
registers configuration and create the platform devices for
the child port nodes. And the platform devices later will
attach to the corresponding DRM/KMS drivers via name match.
