PCI: rcar-gen2: Drop ARM dependency from PCI_RCAR_GEN2

Since the reliance on ARM-specific struct pci_sys_data was removed, this
driver can be compile-tested on other architectures.

While at it, make the help text a bit more generic, as some members of
the R-Car Gen2 family have a different number of internal PCI
controllers.
