v4: fixed kzalloc error check and modified df func init to return error code
v3: fixed cleanup by adding fini to free up adev df config counters
v2: simplified by removing xgmi references in function names and moving to
generic df function names. fixed issue by removing hardcoded cake tx data
events. streamlined error handling by having df_v3_6_pmc_get_ctrl return
error code.
add pmu attribute groups and structures for perf events.
add sysfs to track available df perfmon counters
fix overflow handling in perfmon counter reads.
