Deprecate contigfree(9) in favour of free(9)
As of 9e6544dd6e02c46b805d11ab925c4f3b18ad7a4b contigfree(9) is no longer
needed and should not be used anymore. We leave a wrapper for 3rd party
code in at least 15.x but remove (almost) all other cases from the tree.
This leaves one use of contigfree(9) untouched; that was the original
trigger for 9e6544dd6e02 and is handled in D45813 (to be committed
seperately later).

Move to a SMMU specific struct for the smmu pmap
This is not managed through the VM subsystem so only needs to hold the
data the SMMU driver needs.

Introduce IOMMU support for arm64 platform.
This adds an arm64 iommu interface and a driver for Arm System Memory
Management Unit version 3.2 (ARM SMMU v3.2) specified in ARM IHI 0070C
document.
Hardware overview is provided in the header of smmu.c file.
The support is disabled by default. To enable add 'options IOMMU' to your
kernel configuration file.
The support was developed on Arm Neoverse N1 System Development Platform
(ARM N1SDP), kindly provided by ARM Ltd.
Currently, PCI-based devices and ACPI platforms are supported only.
The support was tested on IOMMU-enabled Marvell SATA controller,
Realtek Ethernet controller and a TI xHCI USB controller with a low to
medium load only.
Many thanks to Konstantin Belousov for help forming the generic IOMMU
framework that is vital for this project; to Andrew Turner for adding
IOMMU support to MSI interrupt code; to Mark Johnston for help with SMMU
page management; to John Baldwin for explaining various IOMMU bits.
