drivers/perf: riscv-iommu: add risc-v iommu pmu driver
80fe14e 
Add a new driver to support the RISC-V IOMMU PMU. This is an auxiliary
device driver created by the parent RISC-V IOMMU driver.

The RISC-V IOMMU PMU separates the cycle counter from the event counters.
The cycle counter is not associated with iohpmevt0, so a software-defined
cycle event is required for the perf subsystem.

The number and width of the counters are hardware-implemented and must
be detected at runtime.

The performance monitor provides counters with filtering support to
collect events for specific device ID/process ID, or GSCID/PSCID.

PMU-related definitions are moved into the perf driver, where they are
used exclusively.
