[PATCH v2 06/26] PCI: keystone: Move initializations to appropriate places

[Kishon Vijay Abraham I]

No functional change. Move host specific platform_get_resource to
ks_add_pcie_port and the common platform_get_resource (applicable
to both host and endpoint) to probe. This is in preparation for
adding endpoint support to pci-keystone driver.
