Before commit bc0d7fdefec6 ("drm: vkms: Supports to the case where
primary plane doesn't match the CRTC"), the composition was executed on
top of the primary plane. Therefore, the primary plane was not able to
support the alpha channel. After commit bc0d7fdefec6, this is possible,
as the composition is now executed on top of the CRTC.
So, allow all planes to support the alpha channel, making full alpha
blending possible in vkms.

Move the implementation of fb_pgprotect() to fbdev.c and include
<asm/fb.h>. Fixes the following warning:
../arch/x86/video/fbdev.c:14:5: warning: no previous prototype for 'fb_is_primary_device' [-Wmissing-prototypes]
14 | int fb_is_primary_device(struct fb_info *info)
| ^~~~~~~~~~~~~~~~~~~~
Just including <asm/fb.h> results in a number of built-in errors
about undefined function. Moving fb_pgprotect() to the source file
avoids the required include statements in the header. The function
is only called occasionally from fb_mmap(), [1] so having it as static
inline had no benefit.
While at it, fix the codying style in fbdev.c.

Add atomic_get_input_bus_fmts() implementation, tc358768 has a parallel
RGB input interface with the actual bus format depending on the amount
of parallel input data lines.
Without this change when the tc358768 is used with less than 24bit the
color mapping is completely wrong.

The CSC matrices were stored as separate matrix for each colorspace, and
if we wanted a limited or full RGB output.
This created some gaps in our support and we would not always pick the
relevant matrix.
Let's rework our data structure to store one per colorspace, and then a
matrix for limited range and one for full range. This makes us add a new
matrix to support full range BT709 YUV output.

YUV444 and YUV422 actually require the same matrix, but programmed
differently.
We've dealt with it in the past by having two matrices, with the one
for YUV444 reordered to accomodate the hardware.
This gets in the way of subsequent reworks so let's define a function
that will take the coefficients swap into account, and remove the now
redundant YUV444 matrix.

On VC4, the TV margins on the HDMI connector are implemented by scaling
the planes.
However, if only the TV margins or the connector are changed by a new
state, the planes ending up on that connector won't be. Thus, they won't
be updated properly and we'll effectively ignore that change until the
next commit affecting these planes.
Let's make sure to add all the planes attached to the connector so that
we can update them properly.

Move code from ad-hoc fbdev callbacks into DRM client functions
and remove the old callbacks. The functions instruct the client
to poll for changed output or restore the display. The DRM core
calls both, the old callbacks and the new client helpers, from
the same places. The new functions perform the same operation as
before, so there's no change in functionality.
Replace all code that initializes or releases fbdev emulation
throughout the driver. Instead initialize the fbdev client by a
single call to armada_fbdev_setup() after armada has registered its
DRM device. As in most drivers, aramda's fbdev emulation now acts
like a regular DRM client.
The fbdev client setup consists of the initial preparation and the
hot-plugging of the display. The latter creates the fbdev device
and sets up the fbdev framebuffer. The setup performs display
hot-plugging once. If no display can be detected, DRM probe helpers
re-run the detection on each hotplug event.
A call to drm_dev_unregister() releases the client automatically.
No further action is required within armada. If the fbdev framebuffer
has been fully set up, struct fb_ops.fb_destroy implements the
release. For partially initialized emulation, the fbdev client
reverts the initial setup.

This bridge doesn't actually implement HPD due to it being way too slow
but instead expects the panel driver to wait enough to assume HPD is
asserted. However some panels (such as the generic 'edp-panel') expect
the bridge to deal with the delay and pass maximum delay to the aux
instead.
In order to support such panels, add a dummy implementation of wait
that would just sleep the maximum delay and assume no failure has
happened.

Merge all variants of fb_pgprotect() into a single function body.
There are two different cases for MMU systems. For non-MMU systems,
the function body will be empty. No functional changes, but this
will help with the switch to <asm-generic/fb.h>.
