power: smb1390-psy: Configure temperature output buffer to High-Z state 



Configure temperature buffer output of slave CP to high impedance
since in H/W we are only reading temperature for Master CP and
temperature of slave CP is assumed same as that of Master due to
physical proximity between them.
