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.

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

2.7.4
Colibri-T20 can come in 256 MB RAM (with 512 MB NAND) or 512 MB RAM
(with 1024 MB NAND) flavors. Both of them will use the same DTSI
expecting the bootloader to do the fixup of /memory node. However in
case it does not happen, let's stay on safe side by limiting the memory
to 256 MB for both versions of Colibri-T20.

RFT:
Not tested on 512 MB module as I have only the 256 MB one.
Changes since v5:
1. Add "colibri" suffix to iris DTS (suggested by Stefan).
Changes since v4:
1. Drop the 512 suffix from file names (suggested by Stefan).
Changes since v3:
1. Reduce the memory in existing DTSI instead of creating a new one
(suggested by Marcel).
Changes since v2:
1. Do not add new compatible but use everywhere existing
"toradex,colibri_t20-512" (suggested by Rob).
Changes since v1:
1. Fix memory size in tegra20-colibri-256.dtsi (was working fine because
my bootloader uses mem= argument).

2.7.4
Add a generic /memory node in each Tegra DTSI (with empty reg property,
to be overidden by each DTS) and set proper unit address for /memory
nodes to fix the DTC warnings:
arch/arm/boot/dts/tegra20-harmony.dtb: Warning (unit_address_vs_reg):
/memory: node has a reg or ranges property, but no unit name
The DTB after the change is the same as before except adding
unit-address to /memory node.

Remove unneeded address/size cells properties and unit addresses to fix
DTC warnings like:
arch/arm/boot/dts/tegra30-apalis-eval.dtb: Warning (unit_address_vs_reg):
/i2c@7000d000/stmpe811@41/stmpe_touchscreen@0: node has a unit name, but no reg property
arch/arm/boot/dts/tegra30-apalis-eval.dtb: Warning (avoid_unnecessary_addr_size):
/i2c@7000d000/stmpe811@41: unnecessary #address-cells/#size-cells without "ranges" or child "reg" property

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.

Unit address combines all address cells, so this should be 80000000
here. See also the device tree spec (v0.2) which has an example in
chapter 3.4 /memory node.
So this should be:
memory@80000000 {
...
Same with all the board files below.

This should have two address and two size cells I guess. And DDR for all
TK1 start at 0x0 0x80000000...
So here with a default length of 0:
memory@80000000 {
reg = <0x0 0x80000000 0x0 0x0>;
