Might be useful in some tests, where we are not explicitly testing WC
maps, but rather just require something that is "device coherent", which
should also play nice on discrete platforms.

We need this for discrete.
v2(Ashutosh):
- use the new i915_drm_local.h infrastructure, and drop the LOCAL prefix

We will remove support for the legacy mmap ioctl, so handle that
case without rewriting all tests.
When the gem_mmap ioctl is not available, transparently fallback to mmap_offset.
Changes since v1:
- Skip gem_tiled_wc too, as it requires on legacy mmap behavior. (Ashutosh)
- Remove fallback for __gem_mmap__gtt, it's already mmap_offset. (Ashutosh)

In order to find the correct aperture size for the test, we want to pass
the test's device into the query.

Commit b0da8bb705c0 ("lib/i915: for_each_mmap_offset_type()")
introduced a macro that makes it easy to repeat a test body within a
loop for each mmap-offset mapping type supported by v4 of i915 MMAP_GTT
API. However, when run on an older version of the driver, those
subtests are believed to be still repeated for each known mmap-offset
mapping type while effectively exercising GTT mapping type only. As
that may be confusing, fix it.
It has been assumed that the modified macro is still suitable for use
inside gem_mmap_offset test itself. Would that not be case,
gem_mmap_offset could redefine the macro back to its initial form for
internal use.
v2: Move extra condition to a separate function and call it via
for_each_if(), in case we need to fix it again in future (Chris)
v3: Fix blind copy-paste

Move all mmap flavours and support function to separate file in i915
folder. This helps with moving i915 specific functions away from common
libraries.
v2:
- Autotools still exists. (Petri)
- Include gem_mman.h directly. (Chris)
v3:
- Keep includes explicit. (Chris)
