gpio: sa1100: register software node for GPIO controller

Browse source

Define and register a static software node (sa1100_gpiochip_node) for the
SA-1100 GPIO controller during sa1100_init_gpio(). Assign its firmware node
directly to the GPIO chip prior to calling gpiochip_add_data().

This allows StrongARM SA-1100 board setup files to reference the SoC 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.
