Hmm. I see this pattern has appeared in in a few places in
edk2-platforms (primarily around Ipmi): a .inf referencing relative
paths above it in hierarchy.
I much prefer the more common pattern of having the .inf a level up,
because I feel it makes it more explicit which modules actually share
the "common" bit.
This is me stating my preference, I don't know that we have any hard
rules about it.
