usb: dwc2: Restore GUSBCFG in dwc2_get_hwparams()
Previously dwc2_get_hwparams() was changing GUSBCFG and not putting it
back the way it was (specifically it set and cleared FORCEHOSTMODE).
Since we want to move dwc2_core_reset() _before_ dwc2_get_hwparams() we
should make sure dwc2_get_hwparams() isn't messing with things in a
permanent way.
Since we're now looking at GUSBCFG, it's obvious that we shouldn't need
all the extra delays if FORCEHOSTMODE was already set. This will avoid
some delays for any ports that have forced host mode.
