regmap: Try cached read before checking if a hardware read is possible For some register format types we do not provide a parse_val so we can not do a hardware read. But a cached read is still possible, so try to read from the cache first, before checking whether a hardware read is possible. Otherwise the cache becomes pretty useless for these register types.
