[PATCH RFC 1/3] ASoC: re-introduce disable_route_checks flag for OF routes

[Laurentiu Mihalcea <laurentiumihalcea111@gmail.com>]

From: Laurentiu Mihalcea <laurentiu.mihalcea@nxp.com>

The "disable_route_checks" flag was previously removed via commit
dd2395162c07 ("ASoC: remove disable_route_checks") as it wasn't being
used anywhere.

Re-introduce an OF-specific variant of the flag: "disable_of_route_checks"
as this will be used by audio-graph-card2.
