ALSA SoC needs to know connected DAI ID for probing.
It is not a big problem if device/driver was only for sound,
but getting DAI ID will be difficult if device includes both
Video/Sound, like HDMI.
To solve this issue, this patch adds new .get_dai_id callback
on hdmi_codec_ops.
dw-hdmi-i2s will assume that HDMI sound will be connected
to reg = <2>. Then, ALSA SoC side will recognized it as DAI 0
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
/* HDMI Video IN */
};
port@1 {
reg = <1>;
/* HDMI OUT */
};
port@2 {
reg = <2>;
/* HDMI Sound IN */
};
};

The driver is already made of 5 separate source files. Move it to a
newly created directory named synopsys where more Synopsys bridge
drivers can be added later (for the DisplayPort controller for
instance).
