drm/amdgpu/display: restore AUX_DPHY_TX_CONTROL for DCN2.x
Commit 098214999c8f added fetching of the AUX_DPHY register
values from the vbios, but it also changed the default values
in the case when there are no values in the vbios. This causes
problems with displays with high refresh rates. To fix this,
switch back to the original default value for AUX_DPHY_TX_CONTROL.
Fixes: 098214999c8f ("drm/amd/display: Read VBIOS Golden Settings Tbl")
Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1426
