Only try to unhide MEI if the PCI device wasn't found and

Allows to run the utility on Skylake and newer hardware that
do not have RCBA any more.
TODO: Use sideband interface to unhide MEI.

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

pci_lookup_name might return NULL from using format_name internally
which could cause a crash when trying to print that value. We

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.

The intel ME checker tool would segfault if it reaches the end of
the loop without having the dev pointer set. This happens when
it gets to the end of the previous loop without knowing what to do
with any of the devices it sees.
This patch makes sure the pointer is not NULL before accessing it.
