Nikita Yushchenko 7f0ff06c1c pinctrl: When claiming hog, skip maps not served by same device 
When pinctrl device registers, it automatically claims hogs, that is,
maps that pinctrl device serves for itself.

It is possible that in addition to SoC's pinctrl device, other pinctrl
devices get registered. E.g. some gpio expander devies are registered
as pinctrl devices. For such devices, pinctrl maps could be defined
that set up SoC's pins (e.g. interrupt pin for gpio expander). Such
a map will have target device set to gpio expander.

Here is device tree snippet that causes this scenario:

&i2c0 {
	sx1503@20 {
		compatible = "semtech,sx1503q";
		pinctrl-names = "default";
		pinctrl-0 = <&pinctrl_sx1503_20>;
		...
	};
};
...
&iomuxc {
	pinctrl_sx1503_20: pinctrl-sx1503-20 {
		fsl,pins = <
			VF610_PAD_PTB1__GPIO_23         0x219d
		>;
	};
};

Such a map will have target device set to gpio expander. However is not
a hog, it is a regular map that is claimed by core before gpio expander
device is probed.

Thus when looking for hogs, it is not enough to check that map's target
device is set to pinctrl device being registered. Need also check that
map's control device is also set to the same.
