[PATCH] gpio: mxc: fix warning about static allocation of GPIO base

[Catalin Popescu <catalin.popescu@xxxxxxxxxxxxxxxxxxxx>]

Static allocation of GPIO base is deprecated, let gpiolib perform the
dynamic allocation. This is done by initializing base to a negative
value before the registration of the gpio controller.
