With CONFIG_OF=n and CONFIG_COMPILE_TEST=y the rcar pci-e driver fails to
build on arm:
drivers/pci/host/pcie-rcar.c: In function 'pci_dma_range_parser_init':
drivers/pci/host/pcie-rcar.c:1035:16: error: implicit declaration of function 'of_n_addr_cells' [-Werror=implicit-function-declaration]
parser->pna = of_n_addr_cells(node);
^~~~~~~~~~~~~~~
Fix this by adding an inline stub for of_n_addr_cells
While at it also provide a stub for of_n_size_cells for consistency reasons.
