ASoC: sun4i-codec: Distinguish sun4i from sun7i
Introduce mechanism to detect sun7i and provide a different regmap, codec and different controls for it - different compared to sun4i Allwinner A10.
The controls will be extended in a forthcoming patch - it is necessary to distinguish between sun4i and sun7i controls because the mic gains are in different registers.
Renamed SUN4I_CODEC_AC_SYS_VERI to SUN7I_CODEC_AC_DAC_CAL and renamed SUN4I_CODEC_AC_MIC_PHONE_CAL to SUN7I_CODEC_AC_MIC_PHONE_CAL because these are actually not present on Allwinner A10.
Handle quirks by regmap config and codec and select the correct quirks automatically.

I think you also wanted to pass quirks->codec to snd_soc_register_codec?
