This submission consists of 3 patches:
1. Patch 1 replaces sprintf usage with snprintf or sysfs_emit, as applicable.
2. Patch 2 fixes a bug with reading unprogrammed events.
3. Patch 3 adds support for BlueField-3 platform which uses a different
access mechanism.

Patch 3:
v1 -> v2
1. Fixed naming inconsistency with events struct
2. Replaced switch case instance with if else as suggested
3. Used rounddown instead of calculating the value

v2 -> v3
Removed empty lines and added Reviewed-by tag

Shravan Kumar Ramani (3):
  platform/mellanox: mlxbf-pmc: Fix potential buffer overflows
  platform/mellanox: mlxbf-pmc: Fix reading of unprogrammed events
  platform/mellanox: mlxbf-pmc: Add support for BlueField-3

Replace sprintf with sysfs_emit where possible.
Size check in mlxbf_pmc_event_list_show should account for "\0".

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.

Add new access mechanism and list of supported events to program
and read the counters in BlueField-3.
Performance counter blocks being added for BlueField-3 include:
  - Memory Sub-system (mss) which has counters for monitoring
various DRAM and related skylib events
  - Last level Tile, which has 2 sets of counters (llt, llt_miss)
for monitoring Tile and cache metrics
