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 Reviewed-by: Frieder Schrempf <frieder.schrempf@kontron.de> Tested-by: Frieder Schrempf <frieder.schrempf@kontron.de> Signed-off-by: Peter Chen <peter.chen@nxp.com>hifive-unleashed-5.1
