--------------------------------

[ Upstream commit d08c8b85 ]

Root Ports in NXP LX2xx0 and LX2xx2, where each Root Port is a Root Complex
with unique segment numbers, do provide isolation features to disable peer
transactions and validate bus numbers in requests, but do not provide an
actual PCIe ACS capability.

Add ACS quirks for NXP LX2xx0 A/C/E/N and LX2xx2 A/C/E/N platforms.

as a clue that they share the same Device ID namespace]
