Subject: [PATCH 3/3] ARM: BCM5301X: Specify USB 3.0 PHY in DT

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

Driver for Northstar USB 3.0 PHY has been recently added under the name
phy-bcm-ns-usb3. Add binding for it into the DT files.
The only slightly tricky part is BCM47094 which uses different PHY
version and requires different compatible value.
