Lyude needs some patches in 5.6-rc2 and we didn't bring drm-misc-next
forward yet, so it looks like a good occasion.

At the moment, only DRM_MODE_ROTATE_180 is allowed when we try to apply
the rotation from the video mode parameters. It is also useful to allow
DRM_MODE_ROTATE_0 in case there is only a reflect option in the video mode
parameter (e.g. video=540x960,reflect_x).
DRM_MODE_ROTATE_0 means "no rotation" and should therefore not require
any special handling, so we can just add it to the if condition.

Plus extend the kerneldoc a bit to explain how this should be used.
With the previous patch to drop the force restore the main user of
this function is not emphasis on the "I hold the internal master lock
already" aspect, so rename the function to match.

In case of tiled displays, if we hotplug just one connector,
fbcon currently just selects the preferred mode and if it is
tiled mode then that becomes a problem if rest of the tiles are
not present.
So in the fbdev driver on hotplug when we probe the client modeset,
if we dont find all the connectors for all tiles, then on a connector
with one tile, just fallback to the first available non tiled mode
to display over a single connector.
On the hotplug of the consecutive tiled connectors, if the tiled mode
no longer exists because of fbcon size limitation, then return
no modes for consecutive tiles but retain the non tiled mode
on the 0th tile.
Use the same logic in case of connected boot case as well.
This has been tested with Dell UP328K tiled monitor.

Currently we restrict the number of encoders that can be linked to
a connector to 3, increase it to match the maximum number of encoders
that can be initialized(32).
To more effiently do that lets switch from an array of encoder ids to
bitmask.

The named mode could be invalid and then cmdline parser misses to validate
mode's dimensions, happily adding 0x0 mode as a valid mode. One case where
this happens is NVIDIA Tegra devices that are using downstream bootloader
which adds "video=tegrafb" to the kernel's cmdline and thus upstream Tegra
DRM driver fails to probe because of the invalid mode.

Rotations and reflections setup are needed in some scenarios to initialise
properly the initial framebuffer. Some drivers already had a bunch of
quirks to deal with this, such as either a private kernel command line
parameter (omapdss) or on the device tree (various panels).
In order to accomodate this, let's create a video mode parameter to deal
with the rotation and reflexion.

The drm subsystem also uses the video= kernel parameter, and in the
documentation refers to the fbdev documentation for that parameter.
However, that documentation also says that instead of giving the mode using
its resolution we can also give a name. However, DRM doesn't handle that
case at the moment. Even though in most case it shouldn't make any
difference, it might be useful for analog modes, where different standards
might have the same resolution, but still have a few different parameters
that are not encoded in the modes (NTSC vs NTSC-J vs PAL-M for example).

The drm_client_panel_rotation function has been used so far to set the
default rotation based on the panel orientation.
However, we can have more sources of information to make that decision,
starting with the command line that we will introduce later in this series.

The drm_client_rotation has a check on the rotation value, but the
reflections are also stored in the same variable, and the check doesn't
take this into account.
Therefore, even though we might have a valid rotation, if we're also using
a reflection parameter, the test will fail for no particular reason.

The drm_client_modeset_commit_atomic function uses two times the
plane_state variable in inner blocks of code, but the variable has a scope
global to this function.
This will lead to inadvertent devs to reuse the variable in the second
block with the value left by the first, without any warning from the
compiler since value would have been initialized.
Fix this by moving the variable declaration to the proper scope.

struct drm_fb_helper_crtc is now just a wrapper around drm_mode_set so
use that directly instead and attach it as a modeset array onto
drm_client_dev. drm_fb_helper will use this array to store its modesets
which means it will always initialize a drm_client, but it will not
register the client (callbacks) unless it's the generic fbdev emulation.
Code will later be moved to drm_client, so add code there in a new file
drm_client_modeset.c with MIT license to match drm_fb_helper.c.
The modeset connector array size is hardcoded for the cloned case to avoid
having to pass in a value from the driver. A value of 8 is chosen to err
on the safe side. This means that the max connector argument for
drm_fb_helper_init() and drm_fb_helper_fbdev_setup() isn't used anymore,
a todo entry for this is added.
In pan_display_atomic() restore_fbdev_mode_force() is used instead of
restore_fbdev_mode_atomic() because that one will later become internal
to drm_client_modeset.

1. drm_fb_helper->lock

3. drm_client_dev->modeset_mutex
