[PATCH 2/5] PCI: iproc: Fix kernel-doc formatting

["Krzysztof Wilczyński" <kw@linux.com>]

Fix kernel-doc formatting used to describe structs, enum types
and functions in the pcie-iproc.c, pcie-iproc-msi.c and pcie-iproc.h
files.

Also, add documentation for the "mem" member of the struct iproc_pcie,
and the enum values "IPROC_PCIE_IB_MAP_MEM", "IPROC_PCIE_IB_MAP_IO" and
"IPROC_PCIE_IB_MAP_INVALID" of the enum iproc_pcie_ib_map_type.

Thus, resolve the following build time warning related to kernel-doc:

No change to functionality intended.
