drm/msm/dpu: Set vsync source irrespective of mdp top support

Browse source

[ Upstream commit 1ad9880f05 ]

Since DPU 5.x the vsync source TE setup is split between MDP TOP and
INTF blocks. Currently all code to setup vsync_source is only executed
if MDP TOP implements the setup_vsync_source() callback. However on
DPU >= 8.x this callback is not implemented, making DPU driver skip all
vsync setup. Move the INTF part out of this condition, letting DPU
driver to setup TE vsync selection on all new DPU devices.
