clk: sunxi-ng: Mark A523 bus-r-cpucfg clock as critical

Browse Source 
[ Upstream commit 1dba74abf3 ]

bus-r-cpucfg clock is important for peripheral which takes care of
powering CPU cores on and off. Since this operation is done by firmware
(TF-A), mark it as critical. That way Linux won't interfere with that
clock.
