The 'di' variable is never used inside ipu_dc_enable_channel(),
so just remove it.
This fixes the following build warning with W=1:
drivers/gpu/ipu-v3/ipu-dc.c: In function 'ipu_dc_enable_channel':
drivers/gpu/ipu-v3/ipu-dc.c:252:6: warning: variable 'di' set but not used [-Wunused-but-set-variable]

This has never worked properly, as the IRQ got retriggered immediately
on unmask. Remove the IRQ wait dance, as it is apparently safe to disable
the DC channel at any point in time.

If imx-drm is combined with a bridge or panel that requests an
unsupported format, warn and use a default mapping instead of
hanging the machine. The worst that can happen here are wrong
colors.

Use the drm_plane_helper_update/disable() and drm_helper_crtc_mode_set()
transitional atomic helpers. The crtc->mode_set_nofb callback is added
so that the primary plane is no longer tied to the CRTC. Check/update
logics are separated to make sure crtc->mode_set_nofb and plane->atomic_update
are always successful. Also, some necessary logics are tweaked for a smooth
transition.

This cleans up the display controller microcode setup in ipu_dc_init_sync
a little bit. The microcode template words for DI0 and DI1 are properly
separated to avoid a clash when DI1 is active in interlaced mode at the
same time as DI0 in non-interlaced mode.
A comment is added to explain the meaning of the sync counter.

The support for interlaced video modes seems to be broken; we don't use
anything other than the vtotal/htotal from the timing information to
define the various sync counters.
Freescale patches for interlaced video support contain an alternative
sync counter setup, which we include here. This setup produces the
hsync and vsync via the normal counter 2 and 3, but moves the display
enable signal from counter 5 to counter 6. Therefore, we need to
change the display controller setup as well.
The corresponding Freescale patches for this change are:
iMX6-HDMI-support-interlaced-display-mode.patch
IPU-fine-tuning-the-interlace-display-timing-for-CEA.patch
This produces a working interlace format output from the IPU.

This patch consolidates the different interface_pix_fmt, pixel_fmt, pix_fmt,
and pixfmt variables to a common name "bus_format" wherever they describe the
pixel format on the bus between display controller and encoder hardware.
At the same time, it renames imx_drm_panel_format to imx_drm_set_bus_format.

imx-drm internally misused the V4L2_PIX_FMT constants, which are supposed to
describe the pixel format of frame buffers in memory, to describe the pixel
format on the bus between the display controller and the encoder hardware.
Now that MEDIA_BUS_FMT constants are available to drm drivers, use those
instead.

The functions ipu_dc_enable() and ipu_dc_disable() enable/disable the DC
globally in the IPU_CONF register, but the DC is used by multiple clients
on different DC channels. So make sure to only disable/enable the DC
globally based on a use counter.

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.
