freedreno/registers: Add pipe to perfcntr group

Browse source 
With concurrent binning, some counter reads or SEL reg programming needs
to happen explicitly on the BR or BV ring.  For the most part if there
is a "BV_FOO" counter group that should be on the BV ring and the
corresponding "FOO" group on the BR ring.  There are a few exceptions
like "CP" vs "BV_CP" which have different SEL reg offsets for BR vs BV,
rather than the same offsets that should be accessed via the appropriate
aperture.
