Subject: [PATCH 1/2] gpio: vf610: switch to dynamic allocat GPIO base

From: Haibo Chen <haibo.chen@....com>

gpiolib want to get completely rid of static gpiobase allocation,
so switch to dynamic allocat GPIO base, also can avoid warning
message:

[    1.529974] gpio gpiochip0: Static allocation of GPIO base
is deprecated, use dynamic allocation.
