@Werner Thanks!

@Subrata Yes, I understand the motivation behind this change and I agree it's reasonable, but it doesn't correct or fix anything. Originally, the start was inclusive and the end was exclusive, and this change makes both inclusive. I am requesting two things:

1. Update the commit message so that it doesn't say this commit fixes/corrects something. I think "to be consistent with how resource allocator code prints ranges" is a better reason.
2. Also update other files that print MTRR ranges, for the sake of consistency.
