Subject: [PATCH AUTOSEL 6.2 05/45] ASoC: Intel: avs: rt5682: Explicitly define codec format

From: Amadeusz Sławiński <amadeuszx.slawinski@...ux.intel.com>

[ Upstream commit d24dbc865c2bd5946bef62bb862a65df092dfc79 ]

rt5682 is headset codec configured in 48000/2/S24_LE format regardless
of front end format, so force it to be so.
