15906a3984 lib: utils: Rename the prefix in PMU DT properties
As per the DT schema rules, the prefix should be vendor. As the PMU
properties are generic for all vendors, change the prefix to riscv
instead of pmu.

3e8b31aca9 docs: Add device tree bindings for SBI PMU extension
SBI PMU extension requires a firmware to be aware of the event to
counter/mhpmevent mappings supported by the hardware. One approach
is to encode that information in the device tree.

Define a device tree binding that allows a hardware to describe
all the PMU mappings required in concise format.
