I boot-tested this. With &usb_2 and &usb_2_hsphy removed, dmesg still
shows the af64000 DP controller binding and /sys/class/drm shows the
HDMI-A-1 connector as connected, but nothing is displayed on the attached
monitor. With both nodes present, the monitor shows an image.

So removing them stops HDMI from working on this board.
The comment in v3 will be updated to read:

	/* usb_2's combo PHY drives the HDMI bridge over DP; keep the dwc3 enabled. */

Thanks,
