[PATCH 1/2] arm64: PCI: Remove node-local allocations when initialising host controller

[Punit Agrawal <punit.agrawal@arm.com>]

Memory for host controller data structures is allocated local to the
node to which the controller is associated with. This has been the
behaviour since support for ACPI was added in
commit 0cb0786bac15 ("ARM64: PCI: Support ACPI-based PCI host controller").

Drop the node local allocation as there is no benefit from doing so -
the usage of these structures is independent from where the controller
is located.
