Add support to configure multiple pins in each register, existing implementation added by [1] does not support full fledge multiple pin configuration in single register, reports a pin clash when different modules configure different bits of same register. The issue reported and discussed here http://www.spinics.net/lists/arm-kernel/msg235213.html With pinctrl-single,bits-per-mux property specified, use function-mask property to find out number pins to configure. Allocate and register pin control functions based sub mask. Tested on da850/omap-l138 EVM. does not support variable submask for pins. does not support pinconf.
