Subject: [PATCH V2 2/5] ARM: BCM5301X: Specify USB controllers in DT

From: Rafał Miłecki <rafal@...ecki.pl>

There are 3 separated controllers, one per USB /standard/. With PHY
drivers in place they can be simply supported with generic drivers.

V2: Fix node names and reorder ehci with ohci. Thanks Ray!
