ASoC: Intel: hdac_hdmi: add Icelake support

[bardliao]

Add Icelake device id. Also, Icelake's pin2port mapping table is
different from previous platforms. So add .base_nid at drv_data
to use different base for different platforms.

@lgirdwood@plbossart I found something wrong on pin2port mapping. Please don't merge it until I find the rule of pin2port.

[plbossart]

isn't the rule already part of the patch_hdmi.c code

/* There is a fixed mapping between audio pin node and display port. * on SNB, IVY, HSW, BSW, SKL, BXT, KBL: * Pin Widget 5 - PORT B (port = 1 in i915 driver) * Pin Widget 6 - PORT C (port = 2 in i915 driver) * Pin Widget 7 - PORT D (port = 3 in i915 driver) * * on VLV, ILK: * Pin Widget 4 - PORT B (port = 1 in i915 driver) * Pin Widget 5 - PORT C (port = 2 in i915 driver) * Pin Widget 6 - PORT D (port = 3 in i915 driver) */staticintintel_base_nid(structhda_codec*codec)

return5;
}
}
staticintintel_pin2port(void*audio_ptr, intpin_nid)
{
intbase_nid=intel_base_nid(audio_ptr);
if (WARN_ON(pin_nid<base_nid||pin_nid >= base_nid+3))
return-1;
returnpin_nid-base_nid+1; /* intel port is 1-based */
}

@plbossart Yes, and it is why I feel confused. From the role of patch_hdmi.c, the ICL's intel_base_nid should be 5. And the spec also says the same. But it is 4 by reading the nid. So I don't know which one is correct. Actually, I think it is 4 right now, but I don't know if it will be "fixed" to 5 in the future.
