Paulo Zanoni 257e1515e3 brw: null-tile sends don't need to skip L3 on Xe2 and newer 
Despite the information in "Overview of Memory Access" (57046), the L3
seems to be smarter on Xe2+. See 4aa3b2d3ad ("anv: LNL+ doesn't need
the special flush for sparse").

The behavior is the same both with vm_bind and TR-TT.

v2: Add some comments (Caio).
