powerpc/perf: Add new power PMU flag "PPMU_P10_DD1" for power10 DD1
Add a new power PMU flag "PPMU_P10_DD1" which can be used to
conditionally add any code path for power10 DD1 processor version.
Also modify power10 PMU driver code to set this flag only for DD1,
based on the Processor Version Register (PVR) value.
