drm/vc4: Add a getparam ioctl for getting the V3D identity regs.
As I extend the driver to support different V3D revisions, userspace
needs to know what version it's targeting. This is most easily
detected using the V3D identity registers.
v2: Make sure V3D is runtime PM on when reading the registers.
v3: Switch to a 64-bit param value (suggested by Rob Clark in review)
