hfi_core_ping() was added by 2017's
commit 09c2845e8fe4 ("[media] media: venus: hfi: add Host Firmware
Interface (HFI)")
but has remained unused.
Remove it.
It was the only caller of the ->core_ping member of hfi_ops,
so remove it, and the venus_core_ping that it pointed to.
Note I've left pky_sys_ping which seems to be the lowest level
definition of the command.
