lantiq: Add sensible hw-defaults for dwc2
Lantiq driver does not work with autodetected fifo sizes so use ones from original ltq-hcd driver in dwc2. Other values can be autodetected. Signed-off-by: Antti Seppälä <a.seppala@gmail.com> Signed-off-by: Vincent Pelletier <plr.vincent@gmail.com> SVN-Revision: 44674
