Introduce the capability to read the firmware binary names from device-tree
using the firmware-name property if available.
This patch is needed because NPU firmware binaries are board specific since
they depend on the MediaTek WiFi chip used on the board (e.g. MT7996 or
MT7992) and the WiFi chip version info is not available in the NPU driver.
This is a preliminary patch to enable MT76 NPU offloading if the Airoha SoC
is equipped with MT7996 (Eagle) WiFi chipset.
I _think_ you need to add the firmware file names to the end of the
file using MODULE_FIRMWARE(). That gives dracul, or whatever is
building in initramfs, the information it needs to include them.
