Add a modesetting driver for Grain Media GM12U320 based devices
(primarily Acer C120 projector, but there may be compatible devices).

This is based on the fb driver from Viacheslav Nurmekhamitov:
https://github.com/slavrn/gm12u320

This driver uses drm_simple_display_pipe to deal with all the atomic
stuff, gem_shmem_helper functions for buffer management and
drm_fbdev_generic_setup for fbdev emulation, so that leaves the driver
itself with only the actual code for talking to the gm12u320 chip,
leading to a nice simple and clean driver.

Changes in v2:
-Add drm-misc tree to MAINTAINERS
-Drop mode_config.preferred_depth = 24 / fix fbdev support

After migrating several drivers to the generic fbdev
emulation there are no users left of drm_gem_fbdev_fb_create.
Delete the function.

Noticed that there was no callers while browsing
around in the drm_fb* code.

The code that referenced the function was removed by:
commit 13aff184 ("drm/qxl: remove dead qxl fbdev emulation code")

The actual use was removed by:
commit 26d4707d ("drm/qxl: use generic fbdev emulation")

v2:

Conversion from YUV to RGB depends on range (limited or full) and
encoding (BT.601 or BT.709). Current code doesn't consider this and
always uses BT.601 encoding and limited range.

Fix this by introducing new CSC matrices, which are selected based on
range and encoding parameters.

This attempts to address outstanding review feedback from
commit b8a2948f ("drm/panel: simple: Add ability to override typical timing")

Specifically:

* It was requested that I document (in the structure definition) that
  the device tree override had no effect if 'struct drm_display_mode'
  was used in the panel description.  I have provided full Doxygen
  comments for 'struct panel_desc' to accomplish that.
* panel_simple_get_fixed_modes() was thought to be a confusing name,
  so it has been renamed to panel_simple_get_display_modes().
* panel_simple_parse_override_mode() was thought to be better named as
  panel_simple_parse_panel_timing_node().

Although the DisplayPort spec explicitly calls out the 1.62/2.7/5.4/8.1
link rates, the value of LINK_BW_SET is calculated.  The DisplayPort
spec says "Main-Link Bandwidth Setting = Value x 0.27Gbps/lane".

A bridge that we're looking to upstream uses 6.75Gbps rate (value 0x19)
[1], and that precludes it from using these functions.

This 6.75Gbps rate is defined in the spec as (credit to Ville for posting this):
  A MyDP Source device, upon reading the MAX_LINK_RATE register of the
  downstream DPRX programmed to 19h (which can be the case only for a
  MyDP-to-Legacy or MyDP-to-DP lane count converter) can program the
  LINK_BW_SET register (DPCD Address 00100h) to 19h to enable 6.75Gbps/lane."

So to avoid failing on legitimate rates in the future, this patch calculates thevalues according to spec instead of restricting these values to one of the
DP_LINK_BW_* #defines.

No functional change for the well-defined values, but we lose the
warning (and return the correct value) for ill-defined bw values.

Drop use of the deprecated drmP.h header.
While doing so used the opportunity
to clean up a little so includes are now
sorted and removed unused include files.
In a few cases added some forwards to allow header
files to built in different include order.

As the set of shared fences is not being changed during reallocation of
the reservation list, we can skip updating the write_seqlock.

The opening comment mark "/**" is reserved for kernel-doc comments, so
it will generate warnings for comments that are not kernel-doc with
"make W=1". For example,

This should be more future-proof if we ever encounter a device with two
of these bridges.

Each iteration of for_each_available_child_of_node puts the previous
node, but in the case of a break from the middle of the loop there is
no put, thus causing a memory leak. Hence add an of_node_put before the
break.
Issue found with Coccinelle.

Drop use of the deprecated header drmP.h.
Make header file self-contained, with only the required set
of include files.
And fixed fallout in remaining files.
Divide include files in blocks and sort them within each block.
