drm/i915/perf: Express OA register ranges with i915_range

Let's use 'struct i915_range' to express sets of b-counter and mux
registers in the perf code.  This makes the code more similar to how we
handle things like multicast register ranges, forcewake tables, shadow
tables, etc. and also lets us avoid needing symbolic register name
definitions for the various range end points.  With this change, many of
the OA register definitions are no longer used in the code, so we can
drop their #define's for simplicity.

v2:  Drop 'inline' from reg_in_range_table().  (Jani)

v3:  Split the first range in gen12_oa_mux_regs[] so that 0xd08 isn't
     whitelisted.  (Umesh)
