87ec849fe9 dcadec: remove scaling in lfe_interpolation_fir
The scaling factor is constant so it is faster to scale the
FIR coefficients in the tables during compilation.

5fdbfcb5b7 dcadsp: split lfe_dir cases
The x86 runs short on registers because numerous elements are not static.
In addition, splitting them allows more optimized code, at least for x86.
