MLK-17481-3: ASoC: fsl: Fix DSP memory mappings
We load DSP firmware from the ARM side at 0x556e8000 but because the
compiler generated memory layout starts at 0x596e8000 we need to do
some fixups.
Thus, each address (in DSP local memory) generated by the compiler
needs to be substracted an offset = 0x596e8000 - 0x556e8000 = 0x4000000.
Because this only happens on QM we will use dts to specify the offset.
