firmware: cs_dsp: Avoid using a u32 as a __be32 in cs_dsp_mock_mem_maps.c

Browse Source 
In cs_dsp_mock_xm_header_drop_from_regmap_cache() for the ADSP2 case read
the big-endian firmware word into a dedicated __be32 variable instead of
using the same u32 for both the big-endian and cpu-endian value.
