Since we changed regmap to be selected and register per bus rather than
via the core only we can't rely on it being enabled by the ASoC core.
Support compiling it out.

When CONFIG_REGMAP_I2C/SPI are m, CONFIG_REGMAP_I2C_MODULE is set in the
pre-processor instead of CONFIG_REGMAP_I2C. This removes SND_SOC_I2C as a
valid option for snd_soc_codec_set_cache_io()'s control parameter, and
causes any ASoC regmap-using codec built as a module to fail to initialize.

In the case of "make da8xx_omapl_defconfig;make", the SPI support is disabled.
Thus calling regmap_init_spi in soc-io.c has below build error.
ERROR: "regmap_init_spi" [sound/soc/snd-soc-core.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2
This patch fixes the build error by adding CONFIG_REGMAP_I2C/CONFIG_REGMAP_SPI
guards for regmap_init_i2c/regmap_init_spi.

Allow drivers to set up their own regmap API structures. This is mainly
useful with MFDs where the core driver will have set up regmap at the
minute, though it may make sense to push the existing regmap setup out
of the core into the drivers.

Remove all the ASoC specific physical I/O code and replace it with calls
into the regmap API. The bulk write code can only be used safely if all
regmap calls are locked with the CODEC lock, we need to add bulk support
to the regmap API or replace the code with an open coded loop (though
currently it has no users...).

In order to facilitate merging with the register map I/O replace the use
of control_data for the bulk writes with direct lookup of the client data
from the device.

For clarity and to help ongoing refactoring in this area create a new file
to contain the physical I/O functions, separating them out from the cache
operations.
