ASoC: cs*: use simple i2c probe function
The i2c probe functions here don't use the id information provided in
their second argument, so the single-parameter i2c probe function
("probe_new") can be used instead.

This avoids scanning the identifier tables during probes.

ASoC: cs42l51: Improve error handling in cs42l51_remove()
When disabling a regulator fails while the device goes away, there is
little we can do and the machine is probably in enough trouble that any
action we'd want to take fails anyhow.

The return value used to be passed on in cs42l51_i2c_remove() (i.e. the
i2c device remove callback). But the i2c core ignores the error code
(apart from emitting a generic warning) and removes the device anyhow.

So return 0 unconditionally in cs42l51_i2c_remove(), and instead of
returning the error code to the upper layer emit a more helpful warning
message. After that nobody is interested any more in the actual error
code, so let cs42l51_remove() return void.

ASoC: cs42l51: replace codec to component
Now we can replace Codec to Component. Let's do it.

Note:
	xxx_codec_xxx()		->	xxx_component_xxx()
	.idle_bias_off = 0	->	.idle_bias_on = 1
	.ignore_pmdown_time = 0	->	.use_pmdown_time = 1
	-			->	.endianness = 1
	-			->	.non_legacy_dai_naming = 1

2cb1e0259f ASoC: cs42l51: re-hook of_match_table pointer
In commit a1253ef6d3fa ("ASoC: cs42l51: split i2c from codec driver"),
the I2C part of the CS42L51 was moved to a separate file, but the
definition of the of_device_id array was left in the driver file
itself, no longer connected to the platform_driver structure using the
.of_match_table pointer.

This commit exports the of_device_id array in cs42l51, and uses it as
.of_match_able in cs42l51-i2c.c. This solution was suggested by Brian
Austin.
