etnaviv: don't drop TS capability on GPUs with MMUv2

Browse Source 
Currently etnaviv disables TS on all MC1.0 GPUs, since the TS unit
doesn't properly take into account the linear window offset with
MC1.0, creating address aliases on MMUv1 that aren't properly dealt
with.

MMUv2 however doesn't have a linear window, so we can safely enable
TS on those GPUs.
