imx233: slightly rework 3D audio setting
The old code made the setting appear as 0dB, 1.5dB, 3dB and 4.5dB when in fact it is 0dB, 3dB, 4.5dB and 6dB. This commit clarifies the code and also fix this at the same time. This imx233 3D enhancement is complete crap anyway but now you can satisfy yourself with 6 dB of pure crap, clearly an enhancement. Change-Id: Ia3e088987c1ff0cdde228905ff70f46476a499a2
