Improve the DTS files by removing all the leading "0x" and zeros to fix the
following dtc warnings:

Warning (unit_address_format): Node /XXX unit name should not have
leading "0x"

and

Warning (unit_address_format): Node /XXX unit name should not have
leading 0s

Converted using the following command:

$ find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec \
sed -i -e "s/@\([0-9a-fA-FxX\.;:#]+\)\s*{/@\L\1 {/g" \
-e "s/@0x\(.*\) {/@\1 {/g" -e "s/@0+\(.*\) {/@\1 {/g" {} +^C

For simplicity, two sed expressions were used to solve each warnings
separately.

To make the regex expression more robust a few other issues were resolved,
namely setting unit-address to lower case, and adding a whitespace before
the the opening curly brace:

https://elinux.org/Device_Tree_Linux#Linux_conventions

This will solve as a side effect warning:

Warning (simple_bus_reg): Node /XXX@<UPPER> simple-bus unit address format
error, expected "<lower>"

Commit f8bf0161 ("ARM: dts: am33xx: Remove skeleton.dtsi usage")
removed the skeleton.dtsi usage since we want to get rid of it.

But this can cause issues when booting a kernel with a boot-loader
that doesn't create a chosen node if this isn't present in the DTB
since the decompressor relies on a pre-existing chosen node to be
available to insert the command line and merge other ATAGS info.
