Add entries to debugfs at /sys/kernel/debug/octeontx2/cpt.

cpt_pc: dump cpt performance HW registers.
Usage: cat /sys/kernel/debug/octeontx2/cpt/cpt_pc

cpt_engines_sts: show cpt engines current state (busy/free status)
Usage:
echo "AE/SE/IE/all" >  /sys/kernel/debug/octeontx2/cpt/cpt_engines_sts
cat /sys/kernel/debug/octeontx2/cpt/cpt_engines_sts

cpt_engines_info: dump cpt engine control registers.
Usage:
echo "AE/SE/IE/all" >  /sys/kernel/debug/octeontx2/cpt/cpt_engines_info
cat /sys/kernel/debug/octeontx2/cpt/cpt_engines_info

cpt_lfs_info: dump cpt lfs control registers.
Usage:
cat /sys/kernel/debug/octeontx2/cpt/cpt_lfs_info

cpt_err_info: dump cpt error registers.
Usage:
/sys/kernel/debug/octeontx2/cpt/cpt_err_info
