Laszlo Ersek 8f35eb92c4 OvmfPkg: AcpiPlatformDxe: enable PCI IO and MMIO while fetching QEMU tables
Now that the previous patches ensure that we can access all PCI devices in
AcpiPlatformDxe, we can enable IO and MMIO decoding for all of them while
we contact QEMU for the ACPI tables. See more details in the patch titled:

  OvmfPkg: introduce gRootBridgesConnectedEventGroupGuid

In particular, this patch will prevent the bug when the 64-bit MMIO
aperture is completely missing from QEMU's _CRS, and consequently Linux
rejects 64-bit BARs with the error message

  pci 0000:00:03.0: can't claim BAR 4 [mem 0x800000000-0x8007fffff 64bit
                    pref]: no compatible bridge window

Laszlo Ersek 04951644cd OvmfPkg: AcpiPlatformDxe: extract common entry point
Currently the entry point functions of both driver builds
(AcpiPlatformDxe.inf and QemuFwCfgAcpiPlatformDxe.inf) directly contain
the logic that is different between the two builds.

Because we're going to restructure the entry point logic soon, we'd have
to duplicate the same new code between both entry point functions.

Push down the logic in which they differ to a new function:
- InstallAcpiTables() [AcpiPlatform.c]
- InstallAcpiTables() [QemuFwCfgAcpiPlatform.c]

and extract a common entry point function:
- AcpiPlatformEntryPoint() [EntryPoint.c]

which we can soon modify without code duplication.

Jordan Justen f186536bdd OvmfPkg/AcpiPlatformDxe: InstallAllQemuLinkedTables => InstallQemuFwCfgTables
This name better aligns with InstallXenTables and InstallOvmfFvTables.

Jordan Justen 53596a72cd OvmfPkg/AcpiPlatformDxe: Assert if AcpiTable protocol is not found
Since the protocol is in the depex, there is no reason to expect we
might fail to locate the protocol.

Jordan Justen 903f52297f OvmfPkg/QemuFwCfgAcpiPlatformDxe: Move entry point to QemuFwCfgAcpi.c
Having this entry point in QemuFwCfgAcpi.c should not cause a problem
for the other driver which supports Xen and older QEMU versions.
