ASoC: rt5640: Constify ACPI device ids and register defaults
Constify the ACPI device ID array and the register map, no need to have them writable at runtime. Also drop the unneeded RT5640_INIT_REG_LEN define. Signed-off-by: Mathias Krause <minipli@googlemail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
