ALSA: hda/cs8409: Increase delay during jack detection
[ Upstream commit 8cd07657177006b67cc1610e4466cc75ad781c05 ]
Commit c8b4f0865e82 reduced delays related to cs42l42 jack
detection. However, the change was too aggressive. As a result
internal speakers on DELL Inspirion 3501 are not detected.
Increase the delay in cs42l42_run_jack_detect() a bit.
