[PATCH v3 2/9] ASoC: codec: cs42l56: Drop cs42l56.h

["Peng Fan (OSS)" <peng.fan@oss.nxp.com>]

From: Peng Fan <peng.fan@nxp.com>

There is no in-tree user of "include/sound/cs42l56.h", so move
'struct cs42l56_platform_data' to cs42l56.c and remove the header file.
And platform data is mostly for platforms that create
devices non using device tree. CS42L56 is a discontinued product,
there is less possibility that new users will use legacy method
to create devices. So drop cs42l56.h to prepare using GPIOD API.
