There are several functions in the FilteringFunctions that should not have DSP extended macros.

P extension instruction does not work with floating point types. But function arm_conv_f32/arm_conv_partial_f32/arm_correlate_f32/arm_correlate_f16 has "#if defined(ARM_MATH_DSP)" ，which impacts on the performance when testing without any extension but the "ARM_MATH_LOOPUNROLL" is defined.
