of/pci: Fix the conversion of IO ranges into IO resources
The ranges property for a host bridge controller in DT describes the
mapping between the PCI bus address and the CPU physical address. The
resources framework however expects that the IO resources start at a pseudo
"port" address 0 (zero) and have a maximum size of IO_SPACE_LIMIT. The
conversion from PCI ranges to resources failed to take that into account,
returning a CPU physical address instead of a port number.
Also fix all the drivers that depend on the old behaviour by fetching the
CPU physical address based on the port number where it is being needed.

PCI: rcar: Fix GPL v2 license string typo
Per license_is_gpl_compatible(), the MODULE_LICENSE() string for GPL v2 is
"GPL v2", not "GPLv2". Use "GPL v2" so this module doesn't taint the
kernel.

PCI: rcar: Remove rcar_pcie_setup_window() resource argument
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.

PCI: rcar: Use correct initial HW settings
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

PCI: Merge multi-line quoted strings
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.
