Subject: [PATCH V4 0/9] Support i.MX8 SoCs pinctrl drivers built as module

There are more and mroe requirements that SoC specific modules should be built
as module in order to support generic kernel image, such as Android GKI concept.

This patch series supports i.MX8 SoCs pinctrl drivers to be built as module,
including i.MX8MQ/MM/MN/MP/QXP/QM/DXL SoCs, and it also supports building
i.MX common pinctrl driver and i.MX SCU common pinctrl driver as module.

Compared to V3, the changes are as below:
	- change the config dependency back to original;
	- use function callbacks for SCU related functions, and all drivers
	  using SCU pinctrl driver need to initialize the function callbacks,
	  pinctrl-imx.c will check the SCU function callback and call it when
	  it is valid, then no build issue when PINCTRL_IMX is built in and
	  PINCTRL_IMX_SCU is built as module.
