here, please use something like:

	if (CONFIG_IS_ENABLED(DM_I2C) && hdmi->ddc_bus) {
		struct udevice *chip;

there are boards that do not enable CONFIG_DM_I2C yet, and we will
see build breakage in such cases:

drivers/built-in.o: In function `hdmi_read_edid':
drivers/video/meson/../dw_hdmi.c:818: undefined reference to `i2c_get_chip'
drivers/video/meson/../dw_hdmi.c:822: undefined reference to `dm_i2c_read'
