firmwaremgr_find_by_node() matches against the device node of the parent
of the device associated to the handler. This is correct for the socfpga
and zyncmp driver, but not for the altera_serial driver. Add a
device_node argument to the handler which is set by the drivers to the
correct device node and match against that.
