Git-commit: af4a25bbe5e7e60ff696ef5c1ec48ab2d51c17c6

References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
Use the newly added TTM's ability to automatically create debugfs entries
for specified placements. This creates debugfs files that can be read to
get information about various TTM resource managers which are used by
vmwgfx.
