pinctrl_request_gpio(). In the pinctrl-single driver, it needs to
configure pins with gpio function mode.

A new gpio function range should be created in DTS file in below.

pinctrl-single,gpio-range = <phandle pin_offset nr_pins gpio_func>;

range: gpio-range {

};

The gpio-ranges property is used in gpio driver and the
pinctrl-single,gpio-range property is used in pinctrl-single driver.

1. gpio-ranges is used for gpio driver in below.
   gpio-ranges = <phandle gpio_offset_in_chip pin_offset nr_pins>
gpio-ranges = < &pmx0 0 89 1 &pmx0 1 89 1 &pmx0 2 90 1
&pmx0 3 90 1 &pmx0 4 91 1 &pmx0 5 92 1>;

2. gpio driver could get pin offset from gpio-ranges property.
   pinctrl-single driver could get gpio function mode from gpio_func
   that is stored in @gpiofuncs list in struct pcs_device.
   This new pinctrl-single,gpio-range is used as complement for

pinctrl: check pinctrl ready for gpio range

pinctrl_get_device_gpio_range() only checks whether a certain GPIO pin
is in gpio range. But maybe some GPIO pins don't have back-end pinctrl
interface, it means that these pins are always configured as GPIO
function. For example, gpio159 isn't related to back-end pinctrl device
in Hi3620 while other GPIO pins are related to back-end pinctrl device.

Append pinctrl_ready_for_gpio_range() that is used to check whether
pinctrl device with GPIO range is ready. This function will be called
after pinctrl_get_device_gpio_range() fails.

If pinctrl device with GPIO range is found, it means that pinctrl device
is already launched and a certain GPIO pin just don't have back-end pinctrl
interface. Then pinctrl_request_gpio() shouldn't return -EPROBE_DEFER in
