Some early initialisation functions (like intel_uc_init_early) would
like to access the table of mmio registers sorted by their powerwell,
which is currently setup later in intel_uncore_init(). Since this is a
static table that now doesn't touch hw, once upon a time we needed to
probe ivb to determine the forcewake register, but now only depends on
pciid (i.e.  gen) we can do the vfunc setup inside init_early, leaving
the mmio setup where it is.
