gpio: gpio-mm: Utilize devm_ functions in driver probe callback
The devm_ resource manager functions allow memory to be automatically
released when a device is unbound. This patch takes advantage of the
resource manager functions and replaces the gpiochip_add_data call with
the devm_gpiochip_add_data call. In addition, the gpiomm_remove function
has been removed as no longer necessary due to the use of the relevant
devm_ resource manager functions.
