Changes since v1
- Refer to AMP gpios always by their define
- Do not try to set codecs format, since the set_fmt callback for the codec was
dropped.
Changes since v2
- The codec prefix was removed from jz4740 codec include file
- This patch accidentally contained a few bits meant for ASoC JZ4740 platform
support patch. Removed them.
