clk: meson: meson8b: mark clk81 as critical

Browse Source 
Disabling clk81 results in an immediate freeze of the whole system. This
can happen "accidentally" when the last child-clock of clk81 is disabled
(in this case the common clock framework also disables clk81, even if it
was only enabled indirectly before).
