drm/mediatek: add ARM_SMCCC dependency

Browse source 
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.
