ARC: [TB10x] Remove redundant abilis,simple-pinctrl mechanism
The TB10x platform port includes a custom mechanism using to set up default pin controller configurations using abilis,simple-default pin configurations of nodes compatible with abilis,simple-pinctrl. This mechanism is redundant with the Linux standard "default" pin configuration, see commit ab78029ecc347debbd737f06688d788bd9d60c1d "drivers/pinctrl: grab default handles from device core". This patch removes the TB10x custom mechanism in favour of the Linux standard.
