Currently, a host perf_event is created for a vPMC functionality emulation.
It’s unpredictable to determine if a disabled perf_event will be reused.
If they are disabled and are not reused for a considerable period of time,
those obsolete perf_events would increase host context switch overhead
The leagcy pmu_ops->msr_idx_to_pmc is only called in kvm_pmu_rdpmc, so
this name is restrictedly limited to rdpmc_idx which could be indexed
exactly to a kvm_pmc. Let's restrict its semantic by renaming the

i.MX8MN has different speed grade definition compared to
i.MX8MQ/i.MX8MM, when fuses are NOT written, the default
speed_grade should be set to minimum available OPP defined
in DT which is 1.2GHz, the corresponding speed_grade value
should be 0xb.

The probe function in the gpio-backlight driver is quite short. If we
pull gpio_backlight_initial_power_state() into probe we can drop two
more fields from struct gpio_backlight and shrink the driver code.
