perf vendor events powerpc: Fix eventcode of power10 JSON events

Fixed the eventcode values in the power10 JSON event files to prepend
"0x" since these are hexadecimal values.

The patch also changes the event description of the PM_EXEC_STALL_LOAD_FINISH
and PM_EXEC_STALL_NTC_FLUSH event and move some events to correct files.

Fixes: 32daa5d7899e ("perf vendor events: Initial JSON/events list for power10 platform")
