octeontx2-af: Dump current resource provisioning status

Added support to dump current resource provisioning status
of all resource virtualization unit (RVU) block's
(i.e NPA, NIX, SSO, SSOW, CPT, TIM) local functions attached
to a PF_FUNC into a debugfs file.

'cat /sys/kernel/debug/octeontx2/rsrc_alloc'
will show the current block LF's allocation status.
