[RESEND v2 PATCH 04/16] usb: musb: Always clear the data toggle bit when configuring ep

[Pali Rohár]

Without this patch clearing was done only when U-Boot was compiled with
MUSB Host Controller. But clearing of data toggle bit is needed also for
MUSB Device Controller otherwise Device Controller does not work correctly.
