Revert "arm64: dts: qcom: sm8250: remove bus clock from the mdss node for sm8250 target"

This reverts commit 001ce9785c0674d913531345e86222c965fc8bf4.

This upstream commit broke AOSP (post Android 12 merge) build
on RB5. The device either silently crashes into USB crash mode
after android boot animation or we see a blank blue screen
with following dpu errors in dmesg:

[  T444] hw recovery is not complete for ctl:3
[  T444] [drm:dpu_encoder_phys_vid_prepare_for_kickoff:539] [dpu error]enc31 intf1 ctl 3 reset failure: -22
