sh: perf events: Add preliminary support for SH-4A counters.
This adds in preliminary support for the SH-4A performance counters. Presently only the first 2 counters are supported, as these are the ones of the most interest to the perf tool and end users. Counter chaining is not presently handled, so these are simply implemented as 32-bit counters. This also establishes a perf event support framework for other hardware counters, which the existing SH-4 oprofile code will migrate over to as the SH-4A support evolves.
