ARM: dts: broadcom: rpi: Switch to V3D firmware clock

Until commit 919d6924ae9b ("clk: bcm: rpi: Turn firmware clock on/off
when preparing/unpreparing") the clk-raspberrypi driver wasn't able
to change the state of the V3D clock. Only the clk-bcm2835 was able
to do this before. After this commit both drivers were able to work
against each other, which could result in a system freeze. One step
to avoid this conflict is to switch all V3D consumer to the firmware
clock.
