[PATCH 1/2] gpio: altera: use of_mm_gpiochip_remove() to fix memory leak

[Masahiro Yamada]

This driver calls of_mm_gpiochip_add() to add a memory mapped gpio
chip.  So, of_mm_gpiochip_remove() should be used when removing it.

The direct call of gpiochip_remove() misses unmapping the register
and freeing the label.
