[4/7] perf vendor events riscv: Add SiFive Bullet version 0x07 events

Commit Message

From: Eric Lin <[e-mail]>

SiFive Bullet microarchitecture cores with mimpid values starting with
0x07 or greater add new PMU events to support debug, trace, and counter
sampling and filtering (Sscofpmf).

All other PMU events are unchanged from earlier Bullet cores.
