Add a common machine soundcard driver probe function that supports both
DSP and AFE-direct usecases and also provides a hook for legacy machine
soundcard driver probe mechanisms.

Note that the hook is there because, even for legacy probe, a lot of the
actual code can still be commonized, hence still reducing duplication
for the legacy devicetree retrocompatibility cases.

This common probe function deprecates all of the inconsistent previous
probe mechanisms and aims to settle all of the MediaTek card drivers on
consistent and common devicetree properties describing wanted DAIs,
device specific DAI configuration and DAI links to codecs found on
each device/board.

This breaks allmodconfig builds:

Oops. Forgot to test this commit without the next one constifying stuff around.
I'll recheck and make this one right. Good catch!

Thanks for notifying!

Cheers,
Angelo
