pinctrl/abx500: add AB8505 sub-driver
Add AB8505 sub driver to the ABx5x family. As the pin controller (also the ABx500 controllers) is an inherent part of the SoC and will prevent boot if not available, select this from the Ux500 SoC Kconfig.

252 * designers didn't apply the same logic on how to select mux in the
253 * ABx500 family.
254 *
255 * As this pins supports at least ALT_B mux, default mux is

265 * means that pin AB9540_PIN_R4 (pin 1) supports 2 mux, so only GPIOSEL
266 * register is used to select the mux. As this pins doesn't support at
267 * least ALT_B mux, default mux is by writing 0 in GPIOSEL bit :
