Current code enables IOMMU from init_iommu_vm0_domain which is called
from vm0/sos boot sequence. For partition mode VMs, this is not called as
VMs are numbered from 1.
This patch adds support to initialize root table pointer for each IOMMU
and enable all IOMMUs from init_iommu. Hence IOMMUs are enabled even
though ACRN does not boot vm0.
This patch also has changes to fix#1270.

emalloc() is called only by construct_mbi() during creating e820 mmap
layout. The switching has two benefits: first, UEFI FW might keep some
memory in pool, unlike call to emalloc(), call to allocate_pool() might
have no impact on e820 mmap; on the other hand, we can remove emalloc()
routine after this switching.

To reduce the call to dynamic memory allocation, the patch tries to
alloate memroy together with hypervisor when hypervisor is being
relocated by efi stub code. The memory allocated will be right at the
end of HV memory. Three structs will be done in this way: 1) boot_ctx,
which saves EFI boot state and is passed to SOS; 2) multiboot_info,
faked multi-boot header for passing boot info to hypervisor; and 3)
multiboot_mmap, e820 mmap structure.
after this, the EFI stub code (which boot hypervisor) will only have 3
to dynamic memory:
1. the call for hv binary and the 3 struct;
2. the call to CPU boot trampoline code;
3. the call to alloc mmap buf when inquery memory layout from UEFI FW;

This is temperory workaround for DM crash when doing fastboot
reboot. In fastboot, it will disable USB host functionality by
disable device respsone to one PCI bar. While DM code just release
the bar in this case. Which break the reboot functionality.
The workaround is to remove the assert to avoid DM abort. This is
safe because reboot will remove all memory range registered.
We will have offiical fixing later.

Per ACPI spec, there are two fundamental types of ACPI tables:
Tables that contain AML code produced from the ACPI Source Language (ASL).
These include the DSDT, any SSDTs, and sometimes OEM-specific tables (OEMx).
Tables that contain simple data and no AML byte code. These types of tables
are known as ACPI Data Tables. They include tables such as the FADT, MADT,
ECDT, SRAT, etc. -essentially any table other than a DSDT or SSDT.
The second type of table, the ACPI Data Table, could be parsed here.
If Kconfig of CONSTANT_ACPI is set to yes, this parser is not needed.

instr_emul.c.
*Modify the formal parameter type in function definition from uint8_t
to char instead of using cast.
*Drop the const declaration for char data in formal parameter.

*update the data missing conversion.
*change type of internal parameter len to avoid casting in npklog.c.

In the current hypervisor hypercall, first all vcpu is
allocated to SOS, vcpu's vm field is initialized to vm0.
When the vcpu is offlined, vcpu will be paused and vcpu's
vm field is set as NULL by DM. When UOS is created, vcpu's
vm field is set as UOS's vm. So when vmcall_vmexit_handler
is invoked, vcpu's vm filed is always non-NULL.
error checking for vm pointer is done in the function
"vmcall_vmexit_handler", vmcall_vmexit_handler will
guarantee that vm is vm0.
So all hypercall functions (these functions is just for handler
hypercall, except vmcall_vmexit_handler) don't need to check
whether invoking vm is NULL and don't need to check whether
invoking vm is vm0 or not.
Remove related invoking vm error checking for hypercall handling.
V1 --> V2:
Add pre-condition for hypercall in the head file.
V2 --> V3:
Add pre-condition for copy_from_gpa and copy_to_gpa.
V3 --> V4:
Add pre-condition both in the head file and source file.

Flat Mode for hub emulation means DM emulates USB devices under hub but
hide hub itself. Under this design the Guest OS cannot see any emulated
hub. So in the perspective of Guest OS, all the emulated devices are
under root hub.
This patch is used to enable feature as mentioned above. And please NOTE,
it is the initial version of hub flat Mode hub emulation, there are one
limitation: only one physical hub is supported. If second physical hub is
connected, the connect and disconnect behavior in second hub may affect
the function of first emulated hub.
The USB HUB device model should be the final long term solution, but it is
very complex. Use flat mode HUB emulation as the short term solution first
to support some USB touch devices which integrated internal HUB.
