PCI: keystone: Use uniform function naming convention
No functional change. Some function names begin with ks_dw_pcie_* and some function names begin with ks_pcie_*. Modify it so that all function names begin with ks_pcie_*. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Signed-off-by: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com>
