rcar_pcie_setup_window() took both the window number and the resource,
which was redundant because we can look up the resource from the window
number.
Remove the "res" argument.

This patch just makes symbol and function name changes to avoid potential
conflicts, along with minor formatting changes.

Although the R-Car PCIe driver works as it is, there are a number of
incorrect settings that this patch corrects. It corrects:
- enabling the PCI Express Extended Cap ID.
- setting Data Link Layer Link Active Reporting Capable.
- terminating list of capabilities.
It also removes enabling the MAC data scrambling as this is the default HW
setting, and removes incorrect code to enable slave bus mastering as this
is done by the PCI core.

The PCI core will have already checked the configuration register address
before calling the {read|write}() methods; so don't check it again in these
methods.

Merge quoted strings that are broken across lines into a single entity.
The compiler merges them anyway, but checkpatch complains about it, and
merging them makes it easier to grep for strings.
No functional change.

This PCIe Host driver currently does not support MSI, so cards fall back to
INTx interrupts.
