ASoC: rt5514: add rt5514 codec driver This is the initial codec driver for rt5514. The codec includes a low power DSP for voice wake up. The register address is incremental by 4 in the DSP memory map. In order to recover the codec settings in the codec mode and manipulate the DSP mode for voice wake up, we use the multi-level register map. One is for ALSA API in codec mode that can be recovered by cache before recording. Another is for DSP related settings that can be accessed with 32bit address of the DSP in the application of voice wake up.

RT5514 audio CODEC
This device supports I2C only.
Required properties:
- compatible : "realtek,rt5514".
- reg : The I2C address of the device.
ASoC: rt5514: Add the MCLK handling The patch adds the control of MCLK that depends on the status of DAPM. Signed-off-by: Oder Chiou <oder_chiou@realtek.com> Signed-off-by: Mark Brown <broonie@kernel.org>

Optional properties:
- clocks: The phandle of the master clock to the CODEC
- clock-names: Should be "mclk"
