This removes potentially machine-specific routing knowledge from the
I2S driverinto the machine drivers, which is better equipped to know
what the appropriate routing configuration is.

Commit ac601555 ("ASoC: Return early with -EINVAL if invalid dai format is

whether the CS4270 should be configured for master or slave operation.

Replace the manual register restore mechanism in cs4270.c and call the
generic snd_soc_cache_sync() handler instead.
This factors code out in favour of core facilities and also fixes a
bus confusion that is most probably caused by intermixing i2c-regmap
functions and i2c_smbus_* accessors.

According to the datasheet:
The BIT[5:4] of ADC Control Register 2 is to control the word width.
00 = 25 Bits
01 = 20 Bits
10 = 16 Bits
11 = Invalid
Thus, the AD1836_ADC_WORD_OFFSET should be defined as 4.

They're all volatile so shouldn't have defaults and as we've got pages
