Add locking and non-locking versions of if_usb_prog_firmware to support programming firmware after and before driver bring-up respectively. Add more suitable error codes for firmware programming process. Add capability checks for persistent features before attempting to use them. Based on patches from Brajesh Dave and Priyank Singh.
