usb: musb: poll ID pin status in dual-role mode in mpfs glue layer
Similar to other platforms using the MUSB driver, PolarFire SoC lacks
an ID pin interrupt event, preventing several OTG-critical status
change events from being exposed. We need to rely on polling to detect
USB attach events for the dual-role port.
The otg state machine implementation is based on Texas Instruments
DA8xx/OMAP-L1x glue layer.
This has been tested on BeagleV-Fire with couple of devices in host mode
and with the Ethernet gadget driver in peripheral mode, in a wide
variety of plug orders.
