Thanks Wasim

I took some liberties with the PciSegmentLib code to get rid of the 
inline functions in Pcie.h - please double check whether that code is 
still correct, and rebase your code before sending new work that applies 
on top of these changes.

Also, I failed to spot this in review, but preprocessor macros that 
resolve to values that are used in arithmetic expressions should really 
all contain outer (), or you will be pulling your hair out figuring out 
where the unexpected values are coming from. I fixed this up while 
committing (all in Pcie.h)
