mfd: ucb1x00: Register software node for GPIO controller
Define a static software node for the UCB1x00 GPIO controller and attach
it to the core MFD device in ucb1x00_probe(). This node will also be
used by the created GPIO chip.
This allows machine subdrivers (such as Assabet evaluation board
support) to reference the UCB1x00 GPIO controller in property entries
when converting legacy platform data to software nodes, resolving pin
bindings directly via the attached firmware node without relying on
name matching.
