ODROID-XU4: phy: exynos5-usbdrd: Calibrating makes sense only for USB2.0 PHY

Browse Source 
PHY calibration is needed only for USB2.0 (UTMI) PHY, so skip calling
calibration code when phy_calibrate() is called for USB3.0 (PIPE3) PHY.

Fixes: d8c80bb3b5 ("phy: exynos5-usbdrd: Calibrate LOS levels for exynos5420/5800")
