Subject: [PATCH AUTOSEL 5.4 101/108] arm64: dts: qcom: msm8998-mtp: Disable funnel 4 and 5

From: Bjorn Andersson <bjorn.andersson@...aro.org>

[ Upstream commit 3498d9c05f804414c4645a2c0bba0187630fe5f0 ]

Disable Coresight funnel 4 and 5, for now, as these causes the MTP to
crash when clock late_initcall disables unused clocks.
