[coreboot] [PATCH] remove namestring trickery

[Rudolf Marek]

Hello,

The  namestring handling in ACPIgen was a big trickery. We were pasing the 
strings as it was a bytestream already. This was a reason for instead of
_PR one had to write _PR_

Or _SB.PCI0 was in fact _SB_PCI0.

This patch adds a proper namestring generation to our ACPIgen generator.
Its used for Name and Scope and Processor now. As bonus, it allows to create a 
multi name paths too. Like Scope(\ALL.YOUR.BASE).

I have no board now, so I cannot test it on real HW. I did some tests which a 
ACPIgen testbench which I'm attaching for future reference.

I dont know what happen to fam10 code, but I think it will need similar change.
