[PATCH V2] soc: bcm: Make PM driver default for BCM2835

[PATCH V2] soc: bcm: Make PM driver default for BCM2835

[Stefan Wahren]

Since commit 52a4adbaebcc ("ARM: bcm283x: Switch V3D over to using the
PM driver instead of firmware.") VC4 on BCM2835 requires the power driver.

Otherwise the driver won't probe and HDMI output stays black:
vc4_v3d 20c00000.v3d: ignoring dependency for device, assuming no driver

I allowed me to applied this to bcm2835-drivers-next.

Please feel to prepare the pull requests for Florian.

Thanks
