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.
