drm/vc4: Consolidate Hardware Revision Check
A new generation of controller has been introduced with the
BCM2711/RaspberryPi4. This generation needs a bunch of quirks, and over
time we've piled on a number of checks in most parts of the drivers.
All these checks are performed several times, and are not always
consistent. Let's create a single, global, variable to hold it and use
it everywhere.
