[PATCH] OvmfPkg/AcpiPlatformDxe: clean up libs and protos in "AcpiPlatformDxe.inf"

[Laszlo Ersek <lersek@redhat.com>]

None of the source files referenced by "AcpiPlatformDxe.inf" #include
"MdePkg/Include/Library/DxeServicesLib.h" or use interfaces declared
therein, so drop DxeServicesLib from [LibraryClasses].

"AcpiPlatformDxe.inf" references "AcpiPlatform.c", which installs ACPI
tables built into the firmware image from under "OvmfPkg/AcpiTables/", in
case dynamically generated ACPI tables are not available from Xen or QEMU.
For this, the driver consumes gEfiFirmwareVolume2ProtocolGuid. Account for
that in [Protocols].
