Set the Power register HSENAB bit based on musb->config->maximum_speed,
so that the glue layer can control MUSB to work in high- or full-speed.

Set musb config->maximum_speed based on the dts setting to control musb
speed.
By default musb works in high-speed mode. Adding
maximum-speed = "full-speed";
to dts usb node will force musb to full-speed mode.
