Sorry, I will add some more detail and explicit description about this patch.

In VF610 board there has not Power Manager module. So if the CONFIG_REGULATOR is
turned on the SGTL5000 cannot be brought up correctly.
If it's turned off there will also some other errors for the SGTL5000 codec driver 
using the CONFIG_REGULATOR mirco not very correctly.

I will enhance this patch later.
Using CONFIG_SND_SOC_FSL_SGTL5000 instead of CONFIG_REGULATOR here just for not affecting other boards.

If not, the " warning: 'XXXXX' defined but not used [-Wunused-function] " log will print out.


This patch will be enhanced later.
