mfd: bcm2835-pm: Add support for BCM2711
In BCM2711 the new RPiVid ASB took over V3D. The old ASB is still present
with the ISP and H264 bits, and V3D is in the same place in the new ASB
as the old one.
As per the devicetree bindings, BCM2711 will provide both the old and
new ASB resources, so get both of them and pass them into
'bcm2835-power,' which will take care of selecting which one to use
accordingly.
Since the RPiVid ASB's resources were being provided prior to formalizing
the bindings[1], also support the old DT files that didn't use
'reg-names.'
