Lars-Peter Clausen a3adb1432d ASoC: sigmadsp: Fix endianness conversion issue
The 'addr' field of the sigma_action struct is stored as big endian in the
firmware file.

Lars-Peter Clausen 38fd54ee38 ASoC: SigmaDSP: Add regmap support
Add support for loading the SigmaDSP firmware using regmap. This allows us
to transparently use SPI or I2C as the transport protocol on devices which
support them.

For now we keep the old I2C support since we have one user of this which is not
straight forward to convert to regmap, due to variable length registers.

Lars-Peter Clausen 48afc5272e ASoC: SigmaDSP: Provide diagnostic error messages
Provide some error messages when loading the firmware fails, so it is possible
to diagnose the reason for the failure.

Lars-Peter Clausen 40216ce7aa ASoC: Move SigmaDSP firmware loader to ASoC
It has been pointed out previously, that the firmware subsystem is not the right
place for the SigmaDSP firmware loader. Furthermore the SigmaDSP is currently
only used in audio products and we are aiming for better integration into the
ASoC framework in the future, with support for ALSA controls for firmware
parameters and support dynamic power management as well. So the natural choice
for the SigmaDSP firmware loader is the ASoC subsystem.
