Subject: [PATCH v3 9/9] ARM: dts: bcm11351: Add corresponding bus clocks
 for peripheral clocks

Following changes in the clock driver, add matching bus clocks for
existing peripheral clocks. Replace the usb_otg_ahb fixed clock with
the real bus clock.

Signed-off-by: Artur Weber <aweber.kernel@...il.com>

Changes in v2:
- Add this patch (BCM281xx bus clocks)
