Subject: MIPS: lantiq: Fix Danube USB clock

From: Mathias Kresin <dev@kresin.me>

commit 214cbc14734958fe533916fdb4194f5983ad4bc4 upstream.

On Danube the USB0 controller registers are at 1e101000 and the USB0 PHY
register is at 1f203018 similar to all other lantiq SoCs. Activate the
USB controller gating clock thorough the USB controller driver and not
the PHY.

This fixes a problem introduced in a previous commit.

Fixes: dea54fbad332 ("phy: Add an USB PHY driver for the Lantiq SoCs using the RCU module")
