Rob Bradford 69b3849bff target/riscv: Add "pmu-mask" property to replace "pmu-num"
Using a mask instead of the number of PMU devices supports the accurate
emulation of platforms that have a discontinuous set of PMU counters.

The "pmu-num" property now generates a warning when used by the user on
the command line.

Rather than storing the value for "pmu-num" convert it directly to the
mask if it is specified (overwriting the default "pmu-mask" value)
likewise the value is calculated from the mask if the property value is
obtained.

In the unusual situation that both "pmu-mask" and "pmu-num" are provided
then then the order on the command line determines which takes
precedence (later overwriting earlier.)
