well, but drivers supporting G72x are very rare.
then why bother to change the common code to affect every driver?

it'd be better to add the constraint only if the period_size_min and
max are non-zero, since most of drivers do NOT want to use this
constraint.
the similar should be applied to the period_bytes constraint if we
add period_size constraint, because they may conflict with each
other.
