MIPS: lantiq: Enable AHB Bus for USB
On Danube and AR9 the USB core is connected though a AHB bus to the main
system cross bar, hence we need to enable the gating clock of the AHB
Bus as well to make the USB controller work.
Fixes: dea54fbad332 ("phy: Add an USB PHY driver for the Lantiq SoCs using the RCU module")
