usb: musb-new: core: set MUSB_POWER_HSENAB in MUSB_POWER for host mode
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. Signed-off-by: Daniel Mack <zonque@gmail.com>
