Thomas Hellstrom fb17f18993 vmwgfx: Restrict number of GMR pages to device limit 
When GMR2 is available, make sure we restrict the number of used GMR pages
to the limit indicated by the device.
This is done by failing a GMRID allocation if the total number of GMR pages
exceeds the limit.
As a result TTM will then start evicting buffers in GMR memory on a
LRU basis until the allocation succeeds.

Thomas Hellstrom 135cba0dc3 vmwgfx: Implement a proper GMR eviction mechanism 
Use Ben's new range manager hooks to implement a manager for
GMRs that manages ids rather than ranges.
This means we can use the standard TTM code for binding, unbinding and
eviction.
