PCI: rcar: Build pci-rcar-gen2.c only on ARM

Browse Source 
The pci-rcar-gen2.c driver (controlled by PCI_RCAR_GEN2) uses struct
pci_sys_data, which only exists on ARM.  Building it on other arches, e.g.,
arm64/shmobile, causes errors like this:

  drivers/pci/host/pci-rcar-gen2.c: In function 'rcar_pci_cfg_base': drivers/pci/host/pci-rcar-gen2.c:112:34: error: dereferencing pointer to incomplete type
    struct rcar_pci_priv *priv = sys->private_data;
                                    ^

Build pci-rcar-gen2.c only on ARM.

Say Y here if you want internal PCI support on R-Car Gen2 SoC.
There are 3 internal PCI controllers available with a single
