Subject: [PATCH v3 03/12] ASoC: sun4i-i2s: Add regmap config to quirks

From: Marcus Cooper <codekipper@...il.com>

The newer SoCs have a larger range than the original SoC that this
driver was developed for. By adding the regmap config to the quirks
then the driver can initialise the managed register map correctly.
