[PATCH 3/3] gpio: mpc8xxx: Use 'devm_gpiochip_add_data()' to simplify the code and avoid a leak

[Christophe JAILLET <christophe.jaillet@wanadoo.fr>]

If an error occurs after a 'gpiochip_add_data()' call it must be undone by
a corresponding 'gpiochip_remove()' as already done in the remove function.

To simplify the code a fix a leak in the error handling path of the probe,
use the managed version instead (i.e. 'devm_gpiochip_add_data()')
