drm/ttm: rename ttm_mem_reg to ttm_resource.
...
This name better reflects what the object does. I didn't rename
all the pointers it seemed too messy.

drm/ttm: rename ttm_mem_type_manager -> ttm_resource_manager.
...
This name makes a lot more sense, since these are about managing
driver resources rather than just memory ranges.

drm/vmwgfx: Introduce a huge page aligning TTM range manager
...
Using huge page-table entries requires that the physical address of the
start of a buffer object is huge page size aligned.
Make a special version of the TTM range manager that accomplishes this,
but falls back to a smaller page size alignment (PUD->PMD, PMD->NORMAL)
to avoid eviction.
If other drivers want to use it in the future, it can be made a
TTM generic helper. Note that drivers can force eviction for a certain
alignment by assigning the TTM GPU alignment correspondingly.
