arm64: dts: kill skeleton.dtsi
While skeleton.dtsi was initially conceived as a simple way to bootstrap writing a dts, it has proven to be problematic: * The #address-cells and #size-cells values used in skeleton.dtsi may not match what a user wants (e.g. when they need to describe a range larger than 4GB). * For dts files where memory nodes have unit-addresses, it adds a redundant /memory node, for which the reg entry may not be appropriately sized (e.g. where #size-cells has been overridden). * For dts files which assume that a bootloader will fill in the memory node(s), no node is present in the dts (and hence there is no attached comment), making it hard to distinguish these cases from bad dts files, and masking any warnings dtc may produce w.r.t. missing nodes. * The default empty /chosen and /aliases are somewhat useless, and it would be preferable for dts to fill these in (e.g. for /aliases/serial0 and /chosen/stdout-path). This patch removes skeleton.dtsi from arm64. There are currently no users, so we can remove it before any appear.
