Slightly re-work the code around cs35l41_generic_fixup() and the component
binding search so that it can be re-used for other amps that use the
component binding mechanism.
The match string is stored in struct scodec_dev_name instead of hardcoding
it in the match function.
The tas2781 does not use the amp index as part of the driver name match.
But its match format string does not include a field for the index, so
snprintf() would safely ignore the p->index argument. Because of this there
is no need for a special match function for this case, the CS35L41 code
can be re-used.

Can someone test that this doesn't break the two TAS2781 fixups?
