Preparation for transition to planes, which use framebuffers for the
cursor image.  We've always done copies from the userspace buffer up
until now for legacy reasons, there's no good reason to do so on the
chipsets this code covers.

We have the ability to move buffers around in the kernel if necessary,
and should probably use it rather than failing if userspace passes us
a non-contig buffer for a plane.

The NOUVEAU_GEM_TILE_NONCONTIG flag from userspace will become a mere
initial placement hint once all the relevant paths have been updated.

The Baseline_ELD_Len field does not include ELD Header Block size.

From High Definition Audio Specification, Revision 1.0a:

	The header block is a fixed size of 4 bytes. The baseline block
	is variable size in multiple of 4 bytes, and its size is defined
	in the header block Baseline_ELD_Len field (in number of
	DWords).

Do not include the header size in Baseline_ELD_Len field. Fix all known
users of eld[2].

While at it, switch to DIV_ROUND_UP instead of open coding it.

Commit 1dce6264 introduced a regression
spotted on several G94 (FDObz #85160). This device seems to expect the
vblank period to be set after setting scale instead of before.

V2: shove this in a separate function

This is a candidate bug-fix for 3.18

Just a bit of OCD cleanup on headers - this function isn't the core
interface any more but just a helper for drivers who haven't yet
transitioned to universal planes. Put the declaration at the right
spot and sprinkle necessary #includes over all drivers.

Maybe this helps to encourage driver maintainers to do the switch.

v2: Fix #include ordering for tegra, reported by 0-day builder.

v3: Include required headers, reported by Thierry.

There's Apple machines out there which (probably completely arbitrarily)
restrict each output path to a particular head.  This causes us to not
be able to locate the output data needed to power on/off the DP output
correctly.

We fix this by passing in a head index we know is valid (as opposed to
"head 0").
