intel: Add 'mode' param to intel_region_map

The 'mode' param is a bitset of GL_MAP_READ_BIT, GL_MAP_WRITE_BIT.

A future commit will perform buffer resolves in intel_region_map().  So,
even though the access mode is irrelevant to the GTT, the extra
information allows us to intelligently avoid unneccessary buffer resolves.
