freedreno/registers: Add json to describe perfctr groups

Browse source 
To generate the perfctr tables we need a bit more information than what
is in the .xml, such as which groups of SELECT regs correspond to which
sets of COUNTER regs, the enum type of the countables (ie. possible
SELECT reg values), etc.

It would be awkward to shoehorn this into an xml schema that is based on
describing registers.  But json is easy to consume.

Field description:
 - chip:   variant enum used for generating correct reg offsets
 - groups: array of entries for each group of counters/countables:
   - name:     group name
   - num:      the number of counters
   - reserved: array of counter indices reserved for KMD use
   - select_offset: Offset of the first selector reg, used in cases
               where same bank of selectors is used for both BR and
               BV
   - select:   the selector reg name
   - counter:  counter name if <reg64>, otherwise use counter_lo and
               counter_hi
   - countable_type: name of <enum> that defines selector reg values
