gpio: altera: Add missed base and label initialisations

During conversion driver to modern APIs the base field initial value
of the GPIO chip was moved from -1 to 0, which triggers a warning.
Add missed base initialisation as it was in the original code.

Initialise the GPIO chip label correctly as it was done by
of_mm_gpiochip_add_data() before the below mentioned change.
