pinctrl: abx500: update device tree bindings 



After force converting the ABx500 bindings in the driver and
device tree sources, also update the binding documentation to
state that we are now using standard bindings.

common pinctrl bindings used by client devices, including the meaning of the

phrase "pin configuration node".



ST Ericsson's pin configuration nodes act as a container for an arbitrary number of

subnodes. Each of these subnodes represents some desired configuration for a

pin, a group, or a list of pins or groups. This configuration can include the

mux function to select on those pin(s)/group(s), and various pin configuration

parameters, such as input, output, pull up, pull down...



The name of each subnode is not important; all subnodes should be enumerated

and processed purely based on their content.



Required subnode-properties:

- ste,pins : An array of strings. Each string contains the name of a pin or

    group.



Optional subnode-properties:

- ste,function: A string containing the name of the function to mux to the

  pin or group.



- generic pin configuration option to use. Example :



	default_cfg {

		ste,pins = "GPIO1";

		bias-disable;

	};



- ste,config: Handle of pin configuration node containing the generic

  pinconfig options to use, as described in pinctrl-bindings.txt in

  this directory. Example :



	pcfg_bias_disable: pcfg_bias_disable {

		bias-disable;

	};



	default_cfg {

		ste,pins = "GPIO1";

		ste.config = <&pcfg_bias_disable>;

	};

ST Ericsson's pin configuration nodes use the generic pin multiplexing

and pin configuration bindings, see pinctrl-bindings.txt
