Dan Minor 3b0b90c4ba Bug 1158741 - Implement a version of omxSP_FFTInv_CCSToR_F32_Sfs in openmax DL's FFT that is not scaled r=padenot 
The new routine actually multiplies by two for consistency with the other FFT
routines in use.

Bug 1158741 added an omxSP_FFTInv_CCSToR_F32_Sfs_unscaled function as an
optimization which performs the same operation as
omxSP_FFTInv_CCSToR_F32_Sfs except it doesn't scale the results by the
length of the FFT. For consistency with other FFT routines used, it does
multiply the results by two.
