Subject: usb: Remove non-DM code in ehci-fsl and xhci
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=a89a4538a1442eb3215935c9cc13db5baa5d196a;p=u-boot.git

usb: Remove non-DM code in ehci-fsl and xhci

The DM_USB migration deadline has passed and this is not used in SPL.
Remove this now unused code.
