<br />
platform/mellanox: mlxbf-pmc: add sysfs_attr_init() to count_clock init<br />
<br />
The lock-related debug logic (CONFIG_LOCK_STAT) in the kernel is noting<br />
the following warning when the BlueField-3 SOC is booted:<br />
<br />
BUG: key ffff00008a3402a8 has not been registered!<br />

The mlxbf_pmc driver must call sysfs_attr_init() during the<br />
initialization of the "count_clock" data structure to avoid<br />
this warning.
