The I2C core always reports a MODALIAS of the form i2c:<foo> even if the
device was registered via OF, this means that exporting the OF device ID
table device aliases in the module is not needed. But in order to change
how the core reports modaliases to user-space, it's better to export it.
Before this patch:
$ modinfo sound/soc/codecs/snd-soc-tfa9879.ko | grep alias
alias: i2c:tfa9879
After this patch:
$ modinfo sound/soc/codecs/snd-soc-tfa9879.ko | grep alias
alias: i2c:tfa9879
alias: of:N*T*Cnxp,tfa9879C*
alias: of:N*T*Cnxp,tfa9879

Even though the tfa9879 driver can probe via device tree trough the
I2C core code, it is preferable to have explicit device tree
bindings instead [1], so add this support.

codec driver and component driver has duplicated callback functions,
and codec side functions are just copied to component side when
register timing. This was quick-hack, but no longer needed.
This patch moves these functions from codec driver to component driver.

i2c_driver does not need to set an owner because i2c_register_driver()
will set it.

In case of error, the function devm_kzalloc() returns NULL
not ERR_PTR(). The IS_ERR() test in the return value check
should be replaced with NULL test.
