[PATCH v4 4/9] ASoC: sun4i-i2s: Reduce quirks for sun8i-h3

[codekipper]

From: Marcus Cooper <codekipper@xxxxxxxxx>

We have a number of flags used to identify the functionality
of the IP block found on the sun8i-h3 and later devices. As it
is only neccessary to identify this new block then replace
these flags with just one.
