avr: use register wrappers that use runtime/volatile.*Uint8 calls

This avoids the //go:volatile pragma on types in Go source code, at
least for AVR targets.

The llvm linker expects some flags to line up in input sections mapped
to a particular output section, which the GNU linker ignored. Make sure
this flag is set in the input section, see:

tools/gen-device-svd: fix bug in previous commit

There was a bug in the generated Go code: padding member numbers would
not increase their count leading to multiple struct members with the
same name.

tools/gen-device-svd: move peripheral list to beginning

It's much easier to scan the source when the peripheral list is at the
front. Go doesn't care about the order of declaration anyway.

tools/gen-device-svd: rewrite with ElementTree

xml.etree.ElementTree is much easier to work with. This also fixes a few
small bugs in the parser. And as an added bonus, device generation got a
lot faster: apprently etree is a lot faster than minidom.

all: change special type __volatile to pragma //go:volatile
...
This is one step towards removing unnecessary special casts in most
cases. It is also part of removing as much magic as possible from the
compiler (the pragma is explicit, the special name is not).
