This commit changes the firmware handling from requesting each firmware file as a ROM module that is checked against a list of known images (including their size) to requesting each file via the local VFS of the 'wifi_drv'. This allows for using the original probing mechanism that tries to select a matching firmware version. The 'repos/dde_linux/src/drivers/wifi/README' file contains more detailed information on how to configure the driver. Issue #4861.
