base-files: add helper functions for adding wlan device entries to board.json
These will be used to give WLAN PHYs a specific name based on path specified in board.json. The platform board.d script can assign a specific order based on available slots (PCIe slots, WMAC device) and device tree configuration. This helps with maintaining config compatibility in case the device path changes due to kernel upgrades. Signed-off-by: Felix Fietkau <nbd@nbd.name>
