broadcom/commmon: add has_accumulators field on v3d_device_info

Even if we can just check for the version on the code, checking for
this field makes several places more readable. So for example, on the
register allocate code we doesn't assign an accumulator because we
don't have accumulators on that hw, instead of because hw version is a
given one.
