ARM: dts: rockchip: Add support for ES8388 to the Radxa Rock 2 

This commit adds the DT definition of the es8388 i2c device
found at address 0x10. It also adds the definition for connecting
the Rockchip I2S to the es8388 analog output.

This commit is based on the initial work that was done by Sjoerd Simons
<sjoerd.simons@collabora.com> with some improvements.
