The MSM DSI driver has dropped support for calling
mdp_kms_funcs::set_split_display() callback. Drop corresponding callback
from the mdp5 driver together with the rest of the infrastructure.

MSM DRM driver already allows one to compile out the DP or DSI support.
Add support for disabling other features like MDP4/MDP5/DPU drivers or
direct HDMI output support.

If pp autorefresh is up (from bootloader splash), we will surely get
vblank and pp timeouts. Ensure it is turned off.

Neither vtotal nor drm_mode_vrefresh contain a value that is
premultiplied by 100 making the x100 variable name incorrect and
resulting in vclks_line to become 100 times larger than it is supposed
to be. The hardware counts 100 clockticks too many before tearcheck,
leading to severe panel issues on at least the Sony Xperia lineup.
This is likely an artifact from the original MDSS DSI panel driver where
the calculation [1] corrected for a premultiplied reference framerate by
100 [2]. It does not appear that the above values were ever
premultiplied in the history of the DRM MDP5 driver.
With this change applied the value written to the SYNC_CONFIG_VSYNC
register is now identical to downstream kernels.

Leaving this at a close-to-maximum register value 0xFFF0 means it takes
very long for the MDSS to generate a software vsync interrupt when the
hardware TE interrupt doesn't arrive. Configuring this to double the
vtotal (like some downstream kernels) leads to a frame to take at most
twice before the vsync signal, until hardware TE comes up.
In this case the hardware interrupt responsible for providing this
signal - "disp-te" gpio - is not hooked up to the mdp5 vsync/pp logic at
all. This solves severe panel update issues observed on at least the
Xperia Loire and Tone series, until said gpio is properly hooked up to
an irq.

Having the probe helper stuff (which pretty much everyone needs) in
the drm_crtc_helper.h file (which atomic drivers should never need) is
confusing. Split them out.
To make sure I actually achieved the goal here I went through all
drivers. And indeed, all atomic drivers are now free of
drm_crtc_helper.h includes.
v2: Make it compile. There was so much compile fail on arm drivers
that I figured I'll better not include any of the acks on v1.
v3: Massive rebase because i915 has lost a lot of drmP.h includes, but
not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h
there was still one, which this patch largely removes. Which means
rolling out lots more includes all over.
This will also conflict with ongoing drmP.h cleanup by others I
expect.
v3: Rebase on top of atomic bochs.
v4: Review from Laurent for bridge/rcar/omap/shmob/core bits:
- (re)move some of the added includes, use the better include files in
other places (all suggested from Laurent adopted unchanged).
- sort alphabetically
v5: Actually try to sort them, and while at it, sort all the ones I
touch.
v6: Rebase onto i915 changes.
v7: Rebase once more.

For DSI cmd-mode and writeback, we need to write the CTL's START
register to kick things off, but we only want to do that once both
the encoder and the crtc have a chance to write their corresponding
flush bits. The difficulty is that when there is a full modeset
(ie. encoder state has changed) we want to defer the start until
encoder->enable(). But if only plane's have changed, we want to do
this from crtc->commit().
The start_mask was a previous attempt to handle this, but it didn't
really do the right thing since atomic conversion.
Instead track in the crtc state that the start should be deferred,
set to try from encoder's (or in future writeback's) atomic_check().
This way the state is part of the atomic state, and rollback can
work properly if an atomic test fails.
