Virtual memory allows display to support flipping to surfaces which
are not allocated contiguously in memory with physical addresses,
instead a 1-4 level page table is used.
This is beneficial because it allows the scattering of large surfaces
to improve memory efficiency and security.

[Why]
It is huge, unmaintainable, needlessly layered, and obsolete

Remove it. All of it. Also remove the i2caux struct in
dc_context and the code that created and destructed it

dc_target does not fit well into DRM framework so removed it.
This will prevent the driver from leveraging the pipe-split
code for tiled displays, so will have to be handled at a higher
level. Most places that used dc_target now directly use dc_stream
instead.
