DSP: Fix uninitialised variable references ( #1477 )

This commit adds initialisation for the variables that can be used
potentially uninitialised so that GCC does not generate warnings while
building the MVE function implementations.

DSP: Remove undefined behavior in post-increment/decrement read ( #1443 )
...
According to the C standard q15_t * and const q15_t * are not compatible
types which, among other things, imply that an object of type const
q15_t * can't be modified by writing to a q15_t ** or vice versa.
Programs doing this are undefined.
Because of this rule all programs using the functions read_q15x2_ia,
read_q15x2_da, read_q7x4_ia, or read_q7x4_da for reading data from an
array of constant elements will be undefined. To solve this it is not
enough to change the type of the function since this will give problems
when reading data from an array of non-const elements. To get a defined
solution I needed to switch from functions to macros to allow the
increment to be done in the original type of the pointer.
