ASoC: fsl: Fix lockups with recent cache changes
The recent series of changes to the caching in the SSI driver have caused a number of problems to appear in some test systems. These are still not fully understood but we're coming up to the merge window so for now let's revert commit 7de2763d9b3 (ASoC: fsl_ssi: Remove .num_reg_defaults_raw from regmap_config) as backing that out seems to resolve the problem on affected systems.
