zork: Update PS8802/PS8818 IN_HPD to match HW changes
Add a global variable board_usbc1_retimer_inhpd that boards can
set to IOEX_USB_C1_HPD_IN_DB or GPIO_USB_C1_HPD_IN_DB_V1 depending
on board version, that is then used by board_ps8802/ps881_mux_set
to enable/disable IN_HPD on the DB retimer.
BUG=b:168884674
BRANCH=zork
TEST=morphius dali + picasso USB-C1 display works
