Subject: riscv: Make legacy counter enum match the HW numbering
X-Git-Tag: v6.6.7~2022^2~13^2~7

riscv: Make legacy counter enum match the HW numbering

RISCV_PMU_LEGACY_INSTRET used to be set to 1 whereas the offset of this
hardware counter from CSR_CYCLE is actually 2: make this offset match the
real hw offset so that we can directly expose those values to userspace.
