phy: samsung: Add support for the Exynos5420 variant of the USB2 PHY
Exynos5420 differs a bit from Exynos5250 in USB2 PHY related registers in
the PMU region. Add a variant for the Exynos5420 case. Till now, USB2 PHY
worked only because the bootloader enabled the PHY, but then driver messed
USB 3.0 DRD related registers during the suspend/resume cycle.
