Move shareable code to common file pcie-rcar.c and the #defines to
pcie-rcar.h so that the common code can be reused with endpoint driver.
There are no functional changes with this patch for the host controller
driver.

This commit renames pcie-rcar.c to pcie-rcar-host.c in preparation for
adding support for endpoint mode. CONFIG_PCIE_RCAR is kept so that arm64
defconfig change can be a separate patch.
With this patch both config options PCIE_RCAR and PCIE_RCAR_HOST will be
available but PCIE_RCAR internally selects PCIE_RCAR_HOST so that bisect
builds wont be affected.
