Subject[PATCH 06/24] PCI: keystone: Move initializations to appropriate places
Date
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.
