3.16.62-rc1 review patch. If anyone has any objections, please let me know.

commit dfd0309fd7b30a5baffaf47b2fccb88b46d64d69 upstream.
pcie->realio.end should be the address of last byte of the area, therefore using resource_size() of another resource is not correct, we must substract 1 to get the address of the last byte.
