PCI: EPF: Add lpci_epc_map_addr for pre-v5.15 Linux kernels

Browse Source 
Build the Tegra PCI vnet driver fails with Linux v5.14 because the
lpci_epc_map_addr() have the incorrect number of arguments.
The arguments to the lpci_epc_map_addr() functions were updated
in Linux v5.12 but the current Tegra PCI EPF driver assumes that they
were updating after Linux v5.14. Update the Tegra PCI EPF driver to
use the correct arguments for v5.12 onwards.
