asoc: wcd-cpe: Set the dma_mask for cpe_device 



Memory allocation for wcd-cpe ramdump fails as memory is
not allocated from CMA reserve leading to CPE configuration
failure.
So force driver to allocate memory from CMA by
initializing the device’s coherent_dma_mask and dma_mask.

Fixes the SVA CPE sound model loading issue on tashalite variants.
