Subject: [PATCH 0/3] ASoC: rockchip: i2s: compatible with different chips

there maybe more than one i2s module inside chip, and these i2s modules
have different channels features.

for example: there are 3 i2s in rk3066, one support 8 channels playback
and 2 channels capture, but the others only support 2 channels playback
and 2 channels capture.

in order to compatible with these various chips, we add playback and
capture property to specify these values.

there are default channels configuration in driver: 8 channels playback
and 2 channels capture. if not add property, we use the default values.

  ASoC: rockchip: add playback property
  ARM: dts: rockchip: add channels properties for i2s
