usb: musb: fix kernel panic during s2ram(v2)
This patch fixes kernel panic during s2ram, which is caused
by the below:
- musb is not put into drv data of musb platform device if
CONFIG_USB_MUSB_HDRC_HCD is defined
- glue layer driver always get musb instance via platform_get_drvdata.
The patch fixes the issue by always puting musb into drv data
of musb platform device, which is doable even the platform device
is a host controller device.
