This patch adds rk3368 otg-port phy configurations.
But actually, we don't use the otg phy configurations
for the time being, because we use dwc_otg_310 driver
for rk3368 otg controller, and this driver doesn't use
generic phy. This patch is useful if we switch to dwc2
driver for rk3368 otg in the feature.
