ALSA: cs5535audio: Use OLPC/Geode basic infrastructure
Use basic infrastructure code; geode_gpio* (rather than indexed i/o EC access), and do an OLPC machine check in olpc_quirk. [dilinger@debian.org: don't return failure in olpc_quirks if !OLPC] [dilinger@debian.org: drop the <B2 workarounds; those machines are EOL'd] Signed-off-by: Jordan Crouse <jordan.crouse@amd.com> Signed-off-by: Andres Salomon <dilinger@debian.org>
