ps8xxx: Fix PD task hang if PS8xxx device is missing
CL:3084331 added logic to retry reading the PS8xxx FW version register
to ensure the chip has woken up from low power mode. If the PS8xxx
device is damaged/missing, there was an unbounded loop so the
initialization never completed, hanging the corresponding PD task.
BUG=b:198619831
BRANCH=none
TEST=Verify herobrine boots AP when the battery and right I/O board are
disconnected. Also observe "LPM recovery failed" reported on the
console for the missing type-C port.
