[PATCH] MIPS: OCTEON: pcie: fix kernel-doc comments

The Cavium OCTEON PCIe driver has 21 function comments that begin with
'/**' but are missing the required kernel-doc function name line, so
they are silently dropped from the generated documentation. Add the
missing 'function_name() -' line to each, and add the missing ':' after
"Returns" so the return documentation is parsed correctly.

No functional change.

Verified with 'scripts/kernel-doc -none', which reports zero warnings
after this change.
