Subject: [PATCH V2] ARM: BCM5301X: Specify PHY of USB 2.0 in DT

Driver for Northstar USB 2.0 PHY was added in 4.7-rc1 by:
commit d3feb4067335 ("phy: bcm-ns-usb2: new driver for USB 2.0 PHY on
Northstar").
It should be used to let EHCI platform driver init PHY.

Signed-off-by: Rafał Miłecki <zajec5@...il.com>

V2: Add usb2_phy as child of root node instead of adding separated phys
    "simple-bus".
