arm64: dts: qcom: sdm630: Add missing MDSS reset

[ Upstream commit 0c1d159 ]

If the OS does not support recovering the state left by the
bootloader it needs a way to reset display hardware, so that it can
start from a clean state. Add a reference to the relevant reset.

It fixes display init issue appeared in Linux v6.17: without reset
device boots into black screen and you need to turn display off/on
to "fix" it. Also sometimes it can boot into solid blue color
with these messages in kernel log:

  hw recovery is not complete for ctl:2
  [drm:dpu_encoder_phys_vid_prepare_for_kickoff:569] [dpu error]enc33
      intf1 ctl 2 reset failure: -22
  [drm:dpu_encoder_frame_done_timeout:2727] [dpu error]enc33 frame
      done timeout
