Shravan Kumar Ramani 3600c0dc0d platform/mellanox: mlxbf-pmc: Fix reading of unprogrammed events

[ Upstream commit 0f5969452e ]

This fix involves 2 changes:
 - All event regs have a reset value of 0, which is not a valid
   event_number as per the event_list for most blocks and hence seen
   as an error. Add a "disable" event with event_number 0 for all blocks.

 - The enable bit for each counter need not be checked before
   reading the event info, and hence removed.
