[U-Boot] [PATCH] usb: musb-new: core: set MUSB_POWER_HSENAB in MUSB_POWER for host mode

[Daniel Mack]

This bit allows the MUSB controller to negotiate for high-speed mode when
the device is reset by the hub. If unset, Babble errors occur with
high-speed mass storage devices right after the first packet. This condition
is not caught by the interrupt handles in U-Boot, so no recovery is done,
and the USB communication is stuck.

To fix this, set the bit unconditionally, not only for
CONFIG_USB_GADGET_DUALSPEED but also for host-only modes.
