drm/mediatek: add ARM_SMCCC dependency
ARM SMCCC is only set for ARMv7 and ARMv8 CPUs, but we currently allow the driver to be build for older architecture levels as well, which results in a link failure: drivers/gpu/built-in.o: In function `mtk_hdmi_hw_make_reg_writable': :(.text+0x1e737c): undefined reference to `arm_smccc_smc' This adds a Kconfig dependency. The patch applies on my two previous fixes that are not yet applied, so please apply all three to get randconfig builds to work correctly.
