lcd: add lcd/power debug node [1/2]
PD#SWPL-1005 Problem: add lcd/power debug node Solution: 1,add lcd/power node to control lcd power on/off sequence 2,change old lcd/power to lcd/power_step Verify: verified by t962x_r311 Change-Id: I0b10caa4cbd8f7ce489f3ceef7780dba2e0b00dc Signed-off-by: Shaochan Liu <shaochan.liu@amlogic.com>
