regmap: add regmap_parse_val api
In some cases, we need regmap's format parse_val function to do be/le translation according to the bus configuration. For example, snd_soc_bytes_put() uses regmap to write/read values, and use cpu_to_be() directly to covert MASK into big endian. This is a defect, and should use regmap's format function to do it according to bus configuration. Signed-off-by: Nenghua Cao <nhcao@marvell.com> Signed-off-by: Mark Brown <broonie@linaro.org>
