Subject: [PATCH 0893/1085] ARM: dts: Add CM5 DTS support
The CM5 is a platform that will appear in multiple boards, each of
which may have different connectivity. Split the CM5 DTS into a common
cm5.dtsi and board-specific dts files, where the CM5 DTS file (the one
loaded by the firmware by default) is an alias for the CM5IO DTS file.
