phy: samsung: Merge Kconfig for Exynos5420 and Exynos5250

Exynos5420 variant of USB2 PHY is handled by the same code as the
Exynos5250 one. Introducing a separate Kconfig symbol for it was an
over-engineering, which turned out to cause build break for certain
configurations:

ERROR: modpost: "exynos5420_usb2_phy_config" [drivers/phy/samsung/phy-exynos-usb2.ko] undefined!

Fix this by removing PHY_EXYNOS5420_USB2 symbol and using
PHY_EXYNOS5250_USB2 also for Exynos5420 SoCs.
