gpio: gemini: augment DT bindings 



The DT bindings assumed that this IP block was coming from
Cortina Systems, which turns out not to be true. It is a
standard IP block from Faraday Technology and also used in the
Moxa moxart SoC.

We augment the bindings to cover all existing parts and rename
it after the IP block. This involves deleting the old Moxa
bindings that now are contained in this binding.

MOXA ART GPIO Controller



Required properties:



- #gpio-cells : Should be 2, The first cell is the pin number,

		the second cell is used to specify polarity:

			0 = active high

			1 = active low

- compatible : Must be "moxa,moxart-gpio"

- reg : Should contain registers location and length

		#gpio-cells = <2>;

		compatible = "moxa,moxart-gpio";

		reg =	<0x98700000 0xC>;
