From: Yassine Oudjana <y.oudjana@xxxxxxxxxxxxxx>
Having DSI PHY clocks listed in the MMCC node while MDSS is disabled makes
it defer probe indefinitely, resulting in simplefb and other blocks that
depend on its clocks to defer probe as well. Remove DSI PHY clocks from
MMCC to let it probe with MDSS disabled.
Fixes: 48aa636285ad ("arm64: dts: qcom: msm8996: add clocks to the MMCC device node")
