ARM: dts: rockchip: Add shared file for audio on rk3288-veyron boards
Set i2s block to "okay", add sound node for max98090 with gpios for HP and Mic detect and pinctrl, and add a max98090 device and ts3a227e to the correct i2c bus. Signed-off-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> Signed-off-by: Heiko Stuebner <heiko@sntech.de>
