[PATCH v5 5/9] reset: amlogic: use reset number instead of register count

[Jerome Brunet]

The reset driver from audio clock controller may register less
reset than a register can hold. To avoid making any change while
switching to auxiliary support, use the number of reset instead of the
register count to define the bounds of the reset controller.
