When the media subsystem is built as a loadable module, a built-in
DRM driver cannot use the cec notifiers:
drivers/gpu/drm/exynos/exynos_hdmi.o: In function `hdmi_get_modes':
exynos_hdmi.c:(.text.hdmi_get_modes+0x80): undefined reference to `cec_notifier_set_phys_addr_from_edid'
drivers/gpu/drm/exynos/exynos_hdmi.o: In function `hdmi_remove':
exynos_hdmi.c:(.text.hdmi_remove+0x24): undefined reference to `cec_notifier_set_phys_addr'
exynos_hdmi.c:(.text.hdmi_remove+0x38): undefined reference to `cec_notifier_put'
This adds a Kconfig dependency to enforce the HDMI driver to also
be a loadable module in this case.
