[PATCH v2] ALSA: ctxfi: constify rsc ops structures

[Julia Lawall]

The various rsc ops structures are never modified, so declare them as
const.

Done with the help of Coccinelle.

Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx>

v2: This does the following types all at once: dao_rsc_ops, dai_rsc_ops,
amixer_rsc_ops, src_rsc_ops, srcimp_rsc_ops, rsc_ops.  Most of these types
are only used in specific files, but the rsc_ops structures appear in all
of the files, so just do them all at once.  This patch thus also replaces
the one with the subject "ALSA: ctxfi: constify dao and dai rsc ops structures"
