The eDP panel must be powered up for aux transactions, so power it
up for detect and mode probe functions, otherwise power it up or
down based on dpms.

v2:
- only mess with eDP panel on DCE4+
- only mess with eDP panel on eDP connectors, not all DP connectors
v3:
- be extra careful to only mess with eDP panels on eDP connectors
v4:
- avoid possible null derefernce if a connector has not been
assigned to the encoder

If there was no connector mapped to the encoder, atombios_get_encoder_mode()
returned 0 which is the id for DP.  Return something sane instead based on
the encoder id.  This avoids hitting the DP paths on non-DP encoders.

Tiled buffers have the same alignment requirements regardless of
whether the surface is for db, cb, or textures.  Previously, the
calculations where inconsistent for each buffer type.

- Unify the alignment calculations in a common function
- Standardize the alignment units (pixels for pitch/height/depth,
bytes for base)
- properly check the buffer base alignments

The CS checker had some incorrect alignment requirements for 2D surfaces,
this made rendering to mipmap levels that were 2D broken.

Also the CB height was being worked out from the BO size, this doesn't work
at all when rendering mipmap levels, instead we work out what height userspace
wanted from slice max and use that to check it fits inside the BO, however
the DDX send the wrong slice max for an unaligned buffer so we have to workaround
for that even though its a userspace bug.

We should not allocate any object into unmappable vram if we
have no means to access them which on all GPU means having the
CP running and on newer GPU having the blit utility working.

This patch limit the vram allocation to visible vram until
we have acceleration up and running.

Note that it's more than unlikely that we run into any issue
related to that as when acceleration is not woring userspace
should allocate any object in vram beside front buffer which
should fit in visible vram.

V2 use real_vram_size as mc_vram_size could be bigger than
   the actual amount of vram
