phy: Select PHY_EXYNOS_MIPI_VIDEO by default for ARCH_EXYNOS

Instead of requiring user to figure out when PHY_EXYNOS_MIPI_VIDEO needs
to be selected select it by default for Exynos SoCs. Also enable it when
COMPILE_TEST is selected. If required the MIPI CSIS/DPHY driver can be
then disabled or compiled in as module.
