Remove the usage of skeleton.dtsi in the remaining dts files. It was
deprecated since commit 9c0da3cc61 ("ARM: dts: explicitly mark
skeleton.dtsi as deprecated"). This will make adding a unit-address to
memory nodes easier.
The main tricky part to removing skeleton.dtsi is we could end up with
no /memory node at all when a bootloader depends on one being present. I
hacked up dtc to check for this condition.
