greybus: firmware: Improve test application
It can take arguments not and we can perform all the operations with a single binary, sorry for missing that initially. Usage: ./firmware <gb-fw-mgmt-X> <type: interface/backend> <firmware-tag> <timeout> And all of them have default values, etc. Tested with a semco 13 MP module.
