Subject: [PATCH 1/2] phy: Kconfig: Re-organize Exynos USB 2.0 PHY configs

Since the USB 2.0 PHYs are required only with EHCI/OHCI USB drivers,
make it depend on them and default to ARCH_EXYNOS as they are meant
for Exynos platforms. Also, make the sub-drivers silent options enabling
them based on the SoC platforms that they are meant to work with. This
will make life easier for end users who do not have any way knowing the
dependencies.
