[PATCH v2 3/3] arm: dts: Add support for ES8323 to the Firefly-RK3288

[Romain Perier <romain.perier@collabora.com>]

This commit adds the DT definition of the es8323 i2c device found at
address 0x10. It also adds the definition for connecting the Rockchip
I2S to the es8323 analog output.

Signed-off-by: Romain Perier <romain.perier@collabora.com>

Changes in v2:
- Add the pinctrl headphone, that was previously in conflict with otp pins
- Renamed sound_es8323 to sound_i2s
- Added the property rockchip,routing
