Alper Nebi Yasak 297fd4f2ef AECM: MIPS: Use uintptr_t for pointer arithmetic ...

Trying to compile the MIPS-specific AECM audio processing file for
mips64el on Debian results in the following errors:

Presumably, this file was written for 32-bit MIPS so the author used
uint32_t to do pointer arithmetic over these arrays. Fix the errors by
using uintptr_t to work with pointers.
