Adds support for the Hyper-V SCSI controller as part of the hyperv_scsi
driver. This driver enables the use of Hyper-V generation 2 VMs as
the SCSI controller is the only storage method supported.
IDE hard disks can be supported in the future on generation 1 VMs by
this driver, but this will require a mechansim to prevent the ATA
bus manager from handling hard disks and conflicting with this one.

Currently when querying ACPI for the PCI interrupt routing table,
PNP0A03 is always used. Some systems such as X99/C610 and newer
HEDT platforms have multiple PCI host bridges, including PCI and
PCIe. This may result in the incorrect PCI bridge being queried
for routing, causing a failure during IO-APIC configuration.
This change moves to query PNP0A08 first, falling back to PNP0A03
as needed for older systems. This should resolve#19981.

Currently the IO-APIC is fully initialized after PCI initialization
resulting in the IO-APIC not being initialized on systems without a
PCI bus (i.e. Hyper-V Gen2 VMs). This change moves IO-APIC
initialization to occur during early init, deferring PCI interrupt
enumeration and routing until after PCI initialization has been
completed.

Some devices such as graphics and PCI passthrough bridges require

Currently the size of the bitmap cursor passed to the accelerant
is the upper bounds coordinate. This is incorrect and should be
the actual size of the cursor.

Currently, a packet being read is split into header and data buffers.
Change to a single buffer to simplify logic in drivers, especially
for those that receive packets with variable sized headers.
This change also implements the pending send size functionality for
the receive buffer.

Fallback to DBG2 if SPCR is not present while discovering UART serial
devices. DBG2 is newer than SPCR but does not provide the same
information, and it appears that both can exist on the same system.
This has only been tested in Hyper-V which exposes DBG2.

Hyper-V does not use the standard hypervisor CPUID leaf for TSC
frequency reporting, causing time drift on Gen1 VMs as the PIT is
considered unreliable. Gen2 VMs do not emulate a PIT and require
the use of this MSR.
