There is nothing to say that the obj->base.size is actually a multiple
of the block_size.
v2: Use round_up() as block_size is a power-of-two

Currently we insert a arbitration point every 128MiB during a blitter
copy. At 8GiB/s, this is around 30ms. This is a little on the large side
if we need to inject a high priority work, so reduced it down to 8MiB or
roughly 1ms.
v2: Don't forget both fill/copy.

A virtual engine itself does not have a batch pool, but we can gleefully
use any of its siblings instead.

Make sure that when submitting requests, we always serialize against
potential vma moves and clflushes.
Time for a i915_request_await_vma() interface!

We can already clear an object with the blt, so try to do the same to
support copying from one object backing store to another. Really this is
just object -> object, which is not that useful yet, what we really want
is two backing stores, but that will require some vma rework first,
otherwise we are stuck with "tmp" objects.

As pointed out by Chris, with our current approach we are actually
limited to S16_MAX * PAGE_SIZE for our size when using the blt to clear
pages. Keeping things simple try to fix this by reducing the copy to a
sequence of S16_MAX * PAGE_SIZE blocks.

Currently we just pass in bcs0->engine_context so it matters not, but in
the future we may want to pass in something that is not a
kernel_context, so try to be a bit more generic.

With its original name intel_drv.h the intel_display_types.h header was
superfluously cargo-cult included all over the place, while it's really
mostly about display internals. Remove the unnecessary includes.

Everything about the file is about display, and mostly about types
related to display. Move under display/ as intel_display_types.h to
reflect the facts.
There's still plenty to clean up, but start off with moving the file
where it logically belongs and naming according to contents.
v2: fix the include guard name in the renamed file

Track the currently bound address space used by the HW context. Minor
conversions to use the local intel_context.vm are made, leaving behind
some more surgery required to make intel_context the primary through the
selftests.

The plan is to use the blitter engine for async object clearing when
using local memory, but before we can move the worker to get_pages() we
have to first tame some more of our struct_mutex usage. With this in
mind we should be able to upstream the object clearing as some
selftests, which should serve as a guinea pig for the ongoing locking
rework and upcoming async get_pages() framework.
