This is the support for some particular board rather than for the SoC.

Ick, no!  This should be in a driver for the SoC somewhere, not in the
board.  I've not really read most of the rest of the driver.

Use snd_soc_register_card().

Absolutely no, all this setup of the devices for the SoC should be in
your arch/arm code somewhere.  This should only be a driver for the
board.
