usb: chipidea: imx: add HSIC support
To support imx HSIC, there are some special requirement:
- The HSIC pad is 1.2v, it may need to supply from external
- The data/strobe pin needs to be pulled down first, and after
host mode is initialized, the strobe pin needs to be pulled up
- During the USB suspend/resume, special setting is needed
