With this implementation it's possible to detect the state
of bootguard in intel based systems. Currently it's WIP and
in a testphase. Handle it with care!
Changes done:
* Add support for reading msr
* Read ME firmware version
* Print bootguard state for ME > 9.1
* Make argument -s legacy
* Add argument -b for bootguard (and ME) dumping
* Add argument -m for ME dumping
* Opt out early if CPU is non Intel

In general more ME capabilities are considered harmfull, useless or
unwanted. Therefore an easy overview can be obtained by coloring in red

pci_me_interface_scan was returning (via argument 'name') a pointer
to the interface name which was stored in a stack variable. This
caused part of the name to be printed as garbage stack data in some
situations if stack data was overwritten.
This moves the name buffer to the calling function so it can be accessed
before it gets overwritten.
