e06a532f31 powerpc/perf: Fix the threshold event selection for memory events in power10
[ Upstream commit 66d9b7492887d34c711bc05b36c22438acba51b4 ]

Memory events (mem-loads and mem-stores) currently use the threshold
event selection as issue to finish. Power10 supports issue to complete
as part of thresholding which is more appropriate for mem-loads and
mem-stores. Hence fix the event code for memory events to use issue
to complete.

a64e697cef powerpc/perf: power10 Performance Monitoring support
Base enablement patch to register performance monitoring hardware
support for power10. Patch introduce the raw event encoding format,
defines the supported list of events, config fields for the event
attributes and their corresponding bit values which are exported via
sysfs.

Patch also enhances the support function in isa207_common.c to include
power10 pmu hardware.
