[PATCHv4 1/3] ARM: dts: socfpga: rename gpio nodes

[dinguyen at opensource.altera.com]

From: Dinh Nguyen <dinguyen at opensource.altera.com>

Since the Synopsys GPIO IP can support multiple ports of varying widths, it
would make more sense to have the GPIO node DTS entry as this:

gpio0: gpio at ff708000{
	porta{
	};
};

Also, this is documented in the snps-dwapb-gpio.txt.
