net: fm: Add firmware name parameter
In order to read the firmware from the filesystem, we need a file name.
Read the firmware name from the device tree, using the firmware-name
property. This property is commonly used in Linux to determine the
correct name to use (and can be seen in several device trees in U-Boot).
