Subject: [PATCH] CHROMIUM: HACK: arm64: dts: qcom: sc7180-trogdor: Enable
 overlays for the rest of the strongbads

We think the compositor has resolved the issues with moving overlay
planes between CRTCs.  But before we remove the workaround entirely lets
disable the hack for the rest of the detachables to verify that problems
don't crop up.

TEST=hotplug external display in mirror mode
