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