octeontx2-af: Display all enabled PF VF rsrc_alloc entries.

commit bfef56ff021007d645738405ddb31f20edb2d9b7 from
git@git.assembla.com:cavium/WindRiver.linux.git

Currently, we are using a fixed buffer size of length 2048 to display
rsrc_alloc output. As a result a maximum of 2048 characters of
rsrc_alloc output is displayed, which may lead sometimes to display only
partial output. This patch fixes this dependency on max limit of buffer
size and displays all PF VF entries.
