regmap: Reset cache status when reinitialsing the cache
When we reinitialise the cache make sure that we reset the cache access flags, ensuring that the reinitialised cache is in the default state which is what callers would and do expect given the function name. This is particularly likely to cause issues in systems where there was no cache previously as those systems have cache bypass enabled, as for the wm8994 driver where this was noticed.
