[U-Boot] [PATCH] 85XX: Fix pin muxing for second USB controller

On P1022/P1013 second USB controller is muxed with second
Ethernet controller. The current code to enable second USB
fails to properly clear pinmux bits used by ethernet. As a
result, Linux freezes when this controller is used. This
patch fixes the problem.
