IRTE is freed if ptirq entry is released from remove_msix_remapping() or
remove_intx_remapping(). But if it's called from ptdev_release_all_entries(),
e.g. SOS shutdown/reboot, IRTE is not freed.
This patch adds a release_cb() callback function to do any architectural
specific cleanup. In x86, it's used to release IRTE.
On VM shutdown, vpci_cleanup() needs to remove MSI/MSI-X remapping on
ptirq entries, thus it should be called before ptdev_release_all_entries().

In previous code, only for pre-launched VM, hypervisor would create
vuart console for each VM. But for post-launched VM, no vuart is
created.
In this patch, create vuart according to configuration in structure
acrn_vm_config. As the new configuration is set for pre-launched VM and
post-launched VM, and the vuart initialize process is common for each
VM, so, remove CONFIG_PARTITION_MODE from vuart related code.

According to SDM 10.6.1, if dest fields is 0xffU for register
ICR operation, that means the IPI is for broadcast.
According to SDM 10.12.9, 0xffffffffU of dest fields for x2APIC
means IPI is for broadcast.
We add new parameter to vlapic_calc_dest() to show whether the
dest is for broadcast. For IPI, we will set it according to
dest fields. For ioapic and MSI, we hardcode it to false because
no broadcast for ioapic and MSI.

As vector re-mapping is enabled for pre-launched/partition mode VMs,
there is no more need for separate interrupt routine i.e.
partition_mode_dispatch_interrupt.

Except for few translation structures in x86 IOMMU, all translation
structures are 128-bit. All the translation structures used by ACRN
are 128 bit. So removed multiple definitions and defined a struct
that accomodates 128 bit entries.

This patch is a modified one. It removes the usage
of acrn_vm struct from inside vtd.c.
It also puts struct iommu_domain inside vtd.h,
from vtd.c.
It modifies the signature of init_iommu_domain
in order to remove dependency on acrn_vm from
inside vtd.c.
Incorporated comments from Jason and Eddie.
Changed the name of sos_vm_domain to
fallback_iommu_domain
Removed any reference of sos_vm from vtd.[c|h]
