[PATCH v1] ASoC: rockchip-i2s: add description for rk3308

[Johan Jonker]

The description below is already in use for rk3308.dtsi,
but was somehow never added to a document, so add
"rockchip,rk3308-i2s", "rockchip,rk3066-i2s"
for i2s nodes on a rk3308 platform to rockchip-i2s.yaml.
One of the rk3308 i2s nodes also has a different dma layout,
so change that as well.

The rk3308 i2s nodes also contain the properties
"reset-names" and "resets". Code in the manufacturer tree is
not yet applied in the mainline kernel, so skip them for now.
