PCI: dwc: Replace ATU type macros with common TLP type macros

PCI: dwc: Replace ATU type macros with common TLP type macros

The dwc driver defines its own ATU type macros (PCIE_ATU_TYPE_MEM,
PCIE_ATU_TYPE_IO, PCIE_ATU_TYPE_CFG0, PCIE_ATU_TYPE_CFG1,
PCIE_ATU_TYPE_MSG) with the same numerical values as the newly
introduced common TLP type macros.

Remove the local definitions and switch all DWC users to the common
PCIE_TLP_TYPE_* macros. This eliminates redundancy and improves
consistency across PCI controller drivers.

No functional change intended.
