powerpc/83xx: Do not configure or probe disabled FSL DR USB controllers
On MPC837X CPUs Dual-Role USB isn't always available (for example DR USB pins can be muxed away to eSDHC). U-Boot adds status = "disabled" property into the DR USB nodes to indicate that we must not try to configure or probe Dual-Role USB, otherwise we'll break eSDHC support on targets with MPC837X CPUs.
