[PATCH] gpio: mxs: use dynamic allocation of base

[Dario Binacchi]

Since commit 502df79b860563d7 ("gpiolib: Warn on drivers still using static
gpiobase allocation"), one or more warnings are printed during boot on
systems where static allocation of GPIO base is used:

[    0.136834] gpio gpiochip0: Static allocation of GPIO base is deprecated, use dynamic allocation.
[    0.142753] gpio gpiochip1: Static allocation of GPIO base is deprecated, use dynamic allocation.
[    0.148452] gpio gpiochip2: Static allocation of GPIO base is deprecated, use dynamic allocation.
[    0.154341] gpio gpiochip3: Static allocation of GPIO base is deprecated, use dynamic allocation.
[    0.160097] gpio gpiochip4: Static allocation of GPIO base is deprecated, use dynamic allocation.

So let's follow the suggestion and use dynamic allocation.
