power/rk3399: Change power-off sequence for KD panel
We should turn off PP3300_S0 and then PP1800_S0 to meet
KD panel spec. PP3300_S0 has to be on in S3_WoUSB, so PP1800_S0
also has to be on - let's move PP1800_S0_EN to s0s3_usb_wake_power_seq.
BUG=b:71057948
BRANCH=none
TEST='suspend_stress_test' for 10+ cycles without seeing things go wrong
