The RESOURCE_ATTACH_BACKING virtio GPU command assigns guest-side backing
pages to a host-side resource that was created earlier with the
RESOURCE_CREATE_2D command.
We compose the RESOURCE_ATTACH_BACKING command in the
VirtioGpuResourceAttachBacking() function. Currently this function takes
the parameter
IN VOID *FirstBackingPage
This is only appropriate as long as we pass a (guest-phys) system memory
address to the device. In preparation for a mapped bus master device
address, change the above parameter to
IN EFI_PHYSICAL_ADDRESS BackingStoreDeviceAddress
In order to keep the current call site functional, move the (VOID*) to
(UINTN) conversion out of the function, to the call site.
The "Request.Entry.Addr" field already has type UINT64.
This patch is similar to commit 4b725858de68 ("OvmfPkg/VirtioLib: change
the parameter of VirtioAppendDesc() to UINT64", 2017-08-23).
