[PATCH] PCI: rcar-host: adjust dependencies for ARM builds

[Randy Dunlap]

On ARCH=arm COMPILE_TEST builds, pcie-rcar-host.c uses __clk_is_enable(),
so for ARM builds, it should also depend on COMMON_CLK.

Fixes this build error:
arm-linux-gnueabi-ld: drivers/pci/controller/pcie-rcar-host.o: in function `rcar_pcie_aarch32_abort_handler':
pcie-rcar-host.c:(.text+0xdfc): undefined reference to `__clk_is_enabled'

Fixes: a18f4b6ea50b ("PCI: rcar: Rename pcie-rcar.c to pcie-rcar-host.c")
