According to its datasheet, after reset this codec goes into sleep mode. In this mode, any register accessing should be avoided except for exiting sleep mode. Hence this commit moves SLEEP_CFG access before any register accessing.

This is interesting because our HW team suggested putting the device into sleep mode when doing register writes/reads because they were finding abnormalities in the register settings when the device is active.

I have a local patch that changes this as well that the HW team requested.

Let me run this by the HW team first before applying this patch.
