arm64: dts: rockchip: Add analog audio on ODROID-M1

Browse Source 
On the ODROID-M1, the I2S1 TDM controller is connected to the rk809
codec in I2S mode. It is used to provide a stereo headphones output and
a mono speaker output. A GPIO with an external pullup is used as an
headphone detection input.
