740994542a Update memory layout to accommodate uefi on arm64.
For now, memory layout on arm64 is sparse and is conflict with uefi.
Here, we do some rearrangement to let it compact and compatible with

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.

dcf6d9d731 device_manager: AArch64: add a field to set/get GIC device entity
In AArch64 systems, the state of GIC device can only be
retrieved from `KVM_GET_DEVICE_ATTR` ioctl. Therefore to implement
saving/restoring the GIC states, we need to make sure that the
GIC object (either the file descriptor or the device itself) can
be extracted after the VM is started.

This commit refactors the code of GIC creation by adding a new
field `gic_device_entity` in device manager and methods to set/get
this field. The GIC object can be therefore saved in the device
manager after calling `arch::configure_system`.
