Subject: [PATCH 7/7] parport_pc: Limit the number of PCI BAR pairs to 2

From: "Maciej W. Rozycki" <macro@...am.me.uk>

Decrease the number of PCI BAR pair slots allocated for port subdrivers
from 4 to 2 as none wants more than 2 at this time, reducing the memory
footprint a little.  No functional change.
