From: Zeng Zhaoming <zhaoming.zeng(a)freescale.com>
Add Freescale SGTL5000 codec support
Signed-off-by: Zeng Zhaoming <zhaoming.zeng(a)freescale.com>
---
changes since v2:
1. clean up register default values
2. rewrite codec power up code, add sgtl5000_set_power_regs()
3. rewrite codec clock configure code sgtl5000_set_clock()
4. reimplement PM hooks, restore register by particular order.
5. clean up dapm code, remove dac and adc event hooks.
6. clean up codec private structure, remove unnecessary fields.
7. add comments for uncommon code.
Thanks for Mark's review.
