[PATCH v2 03/10] riscv: Make legacy counter enum match the HW numbering

[Alexandre Ghiti]

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.
