As more and more NXP i.MX chips come out, it becomes harder to maintain ci-hdrc-usb2.yaml if more stuffs like property restrictions are added to this file. This will separate i.MX parts out of ci-hdrc-usb2.yaml and add a new schema for NXP ChipIdea USB2 Controller, also add a common schema. 1. Copy common ci-hdrc-usb2.yaml properties to a new shared chipidea,usb2-common.yaml schema. 2. Move fsl,* compatible devices and imx spefific properties to dedicated binding file chipidea,usb2-imx.yaml.
