ARM: dts: armv7-m: remove skeleton.dtsi include

Remove skeleton.dtsi from the common ARM Cortex-M dtsi. This will allow
us to remove skeleton.dtsi on a per platform basis and get rid of the
unit address warning on the memory nodes without getting duplicate memory
nodes.

See 3ebee5a2 ("arm64: dts: kill skeleton.dtsi") for additional
reasons not to use the skeleton.dtsi.
