Zork: Switch PS8743 from IOEX_USB_C1_DATA_EN to I2C
Align all Zork devices on using I2C control of PS8743 mux mode, and stop
using IOEX_USB_C1_DATA_EN signal/pin. This matches what we were already
doing for Dalboz, and gives power savings in both S0 and S3 when nothing
is plugged in and mux is set to none.
BUG=b:157951317
BRANCH=none
TEST=external display and i2ctrace on ezkinil
