[PATCH 5.19 011/365] drm/amdgpu: Only disable prefer_shadow on hawaii

[Greg Kroah-Hartman]

From: Alex Deucher <alexander.deucher@xxxxxxx>

commit a6250bdb6c4677ee77d699b338e077b900f94c0c upstream.

We changed it for all asics due to a hibernation regression
on hawaii, but the workaround breaks suspend on a polaris12.
Just disable it for hawaii.
