drivers/perf: hisi: Fix wrong value for all counters enable
In L3C uncore PMU drivers, bit16 is used to control all counters enable &
disable. Wrong value is given in the driver and its default value is 1'b1,
it can work because each PMU counter has its own control bits too.
Let's fix the wrong value.
