I don't have a MTP, but on HDK855, "fastboot oem select-display-panel
none" combined with setting the physical switch to HDMI mode (which
switches off the 1440x2560 panel) gets it to not setup the display at
all (just the fastboot command isn't enough).

With HDK865 though that doesn't work and I have a hack to work around it
(writing 0 to INTF_TIMING_ENGINE_EN early on in boot will stop video
mode scanout and it won't crash).
