[PATCH 2/2] powerpc/perf: Remove l2 bus events from HW cache event array

[Madhavan Srinivasan <maddy@linux.vnet.ibm.com>]

Remove PM_L2_ST_MISS and PM_L2_ST from HW cache event array since
these are bus events. And these needs to be programmed in groups.
Hence remove them.

Fixes: f1fb60bfde65 ('powerpc/perf: Export Power9 generic and cache events to sysfs')
