device connection: Add fwnode_connection_find_match()

device connection: Add fwnode_connection_find_match()

The fwnode_connection_find_match() function is exactly the
same as device_connection_find_match(), except it takes
struct fwnode_handle as parameter instead of struct device.
That allows locating device connections before the device
entries have been created.
