MLK-23372 perf/imx_ddr: correct CLEAR bit definition
ddr_perf_event_stop will firstly call ddr_perf_counter_enable to disable the counter, and then call ddr_perf_event_update to read the counter value. When disable the counter, it will write 0 into COUNTER_CNTL[CLEAR] bit which cause the counter value cleared. Counter value will always be 0 when update the counter. The correct definition of CLEAR bit is that write 0 to clear the counter value. Reviewed-by: Fugang Duan <fugang.duan@nxp.com> Signed-off-by: Joakim Zhang <qiangqing.zhang@nxp.com>
