As noted in commit 3ebee5a2 ("arm64: dts: kill skeleton.dtsi"),
there are a number of problems with skeleton.dtsi, and it would be
prefereable to remove it entirely. As there are a large number of
existing users, fixing these up will take a while.

This patch adds a note to arm's skeleton.dtsi noting that this is the
case, to make this more obvious and hopefully minimize new uptake of
skeleton.dtsi in the mean time.

The USB OTG mode is not supported by Kestone 2 devices, as result, the
USB devices enumeration and detection will not work properly when
kernel is built with CONFIG_USB_DWC3_DUAL_ROLE=y (default for multi
platform build):
 - it's required to load gadget drivers manually to make host mode
work and this confuses current Keystone 2 users
 - device mode is not working, because port can't detect and switch to
peripheral/host mode dynamically.

Hence, specify usb mode explicitly in DT: usb0 = "host" for all KS2
devices and usb1 = "peripheral" for K2E.

The disassembled DTB are almost the same besides an empty chosen
