[SRU][R][PATCH v6 6/8] ASoC: Add a component fixup_controls callback

[Chris Chiu]

From: Charles Keepax <ckeepax at opensource.cirrus.com>

BugLink: https://bugs.launchpad.net/bugs/2163215

A card level fixup_controls callback was added in:

commit df4d27b19b89 ("ASoC: Introduce 'fixup_controls' card method")

This allowed the machine driver to take actions after all the
card controls have been added. However, there are times when a
codec driver would also want to do things like obtain references
to controls for later use, which require all the controls to be
present. Add a component level fixup_controls callback, echoing
the card level option.
