Convert the i.MX8MQ pinctrl binding to DT schema format using json-schema

Signed-off-by: Anson Huang <Anson.Huang@nxp.com>
---
Changes since V1:
	- use "grp$" instead of "-grp$";
	- use space instead of tab for "ref$";
	- add missed "reg" property;
	- remove the "maxItem" for "fsl,pins" to avoid build warning, as the item number is changable.

Sorry, one other thing.

You're good with GPLv9? Plus this is a license change. Do you have 
rights to do so as some of this comes from the old binding doc? If you 
do, then make it:

(GPL-2.0-only OR BSD-2-Clause)

Actually, it looks like you can combine all 3 into a single schema. The 
only diff is the compatible string.

Yes, it should be GPL-2.0, will fix it in V3.
