Remove the usage of skeleton.dtsi because it was deprecated since commit
9c0da3cc61f1 ("ARM: dts: explicitly mark skeleton.dtsi as deprecated").
It also allows later to fix DTC warnings for missing unit name in
/memory nodes.

The /chosen and /aliases nodes are added only when dependent DTSes do
not define them.  Compiled DTB is the same as before this commit.

Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

Changes since v5:
1. New patch, split with skeleton.dtsi removal (suggested by Stefan).

Hm I see, you cannot add unit address here because the board level
device tree do not have it yet... That makes the split indeed a bit less
appealing.

Anyway, now we have it, and I think it is still nice to have a separate
change.
