ipc4: alh.h: handle hw variants directly in alh.h 

The alh.h headers have used SOF platform layer to handle
differences between different Intel ALH generations. In the end
the only difference is the encoding used for DAI index.

Move the variation to ipc4/alh.h directly as this only affects
Intel builds with ALH support.
