[PATCH v1 17/30] ACPICA: actbl2: Add bit constants of the Flags field in the IOVT IOMMU structure

[Pawel Chmielewski]

From: Xianglai Li <lixianglai@xxxxxxxxxxx>

According to the IOVT specification,
define macros for each bit of the Flags field in the IOVT IOMMU structure:

Bit 0: PCI device flag.
	1: The IOMMU is a PCI device.
	0: The IOMMU is a platform device.

Bit 1: Proximity domain valid.
Bit 2: Whether the devices managed by the IOMMU can be classified by
the PCI segment.
	1: All devices under the root PCI bridge can be managed.
	0: Manageable devices are placed in the device entry list.

Bit3: Hardware capability support.
Bit4: MSI interrupt address bypass supported.
Bit5-31: Reserved, must be zero.

The bit constants are used in a linux kernel driver outside of the
ACPICA code.
