b5bcdbaf48 misc: Upgrade to use the vm-memory crate w/ dirty-page-tracking
As the first step to complete live-migration with tracking dirty-pages
written by the VMM, this commit patches the dependent vm-memory crate to
the upstream version with the dirty-page-tracking capability. Most
changes are due to the updated `GuestMemoryMmap`, `GuestRegionMmap`, and
`MmapRegion` structs which are taking an additional generic type
parameter to specify what 'bitmap backend' is used.

The above changes should be transparent to the rest of the code base,
e.g. all unit/integration tests should pass without additional changes.

e4bb6409ae aarch64: Change memory layout for UEFI & ACPI
Before this change, the FDT was loaded at the end of RAM. The address of
FDT was not fixed.
While UEFI (edk2 now) requires fixed address to find FDT and RSDP.
Now the FDT is moved to the beginning of RAM, which is a fixed address.
RSDP is wrote to 2 MiB after FDT, also a fixed address.
Kernel comes 2 MiB after RSDP.

afc83582be aarch64: Enable IRQ routing for legacy devices
On AArch64, interrupt controller (GIC) is emulated by KVM. VMM need to
set IRQ routing for devices, including legacy ones.

Before this commit, IRQ routing was only set for MSI. Legacy routing
entries of type KVM_IRQ_ROUTING_IRQCHIP were missing. That is way legacy
devices (like serial device ttyS0) does not work.

The setting of X86 IRQ routing entries are not impacted.
