Add support to register for GPIO<->pin mapping using a list of non consecutive pins. The core already supports sparse pin range (pins member of struct pinctrl_gpio_range), but it was not possible to register one. If pins is not NULL the core uses it, otherwise it assumes that a consecutive pin range was registered and it uses pin_base. The function gpiochip_add_pin_range() which allocates and fills the struct pinctrl_gpio_range was renamed to gpiochip_add_pin_range_with_pins() and the pins parameter was added. Two new functions were added, gpiochip_add_pin_range() and gpiochip_add_sparse_pin_range() to register a consecutive or sparse pins range. Both use gpiochip_add_pin_range_with_pins().
