[PATCH] gpio: octeon: allocate the GPIO base dynamically

[Orgad Shaneh <orgads@gmail.com>]

The driver registers its chip with base 0, which gpiolib reports on
every boot:

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

Nothing needs the fixed numbers. The only in-tree consumers, the
gpio-leds nodes of the D-Link DSR boards, reference the controller by
phandle; the GPIO interrupts go through the octeon-irq domain; and no
board code uses the legacy integer API. Let gpiolib pick the base. Only
the chip's number in the deprecated sysfs interface changes.

Tested on a CN6335 board, in a 7.3-based tree: the warning is gone and
the chip probes as before.
