ACRN uses global invalidation for all DMAR translation caches. Whenever
a UOS is shutdown or rebooted, it ends up clearing entries in translation
caches belonging to other VMs/domains. This patch adds support for
domain/device level invalidation for DMA translation caches and index
based invalidation for Interrupt Remapping Cache.

Preparing for hybrid mode:
- create vE820 for pre-launched VMs and do other init code when the
vm_config->type is PRE_LAUNCHED_VM.
- create ve820.c for each board because without wrapping by
CONFIG_PARTITION_MODE, ve820_entry[] needs to be visible even when
compiling target boards that haven't enabled pre-launched VMs.
- remove create_prelaunched_vm_e820() from vm.c and implement board
specific function for each $(CONFIG_BOARD)/ve820.c. The reasons being:
- don't need to define ve820_entry[32] for those boards that don't
support pre-launched VMs.
- more importantly, this makes it much easier to create different per-VM
vE820 when it's needed.

platform_acpi_info.h should be BOARD specific so move the header file
to configs/$(CONFIG_BOARD)/ folder.
So the target acpi info file detect process is:
Compiler search for $(CONFIG_BOARD)_acpi_info.h under
hypervisor/arch/x86/$(CONFIG_BOARD)/ first (the file is supposed to be
generated by offline tool so it is not included in original source), if
found, then the file is the target acpi info file. If not and at the
same time the ENFORCE_VALIDATED_ACPI_INFO Kconfig was set, the compiler
will stop and hint user to add target acpi info file by offline tool.
If ENFORCE_VALIDATED_ACPI_INFO was unset, then compiler will continue to
search for platform_acpi_info.h as target acpi info file under
hypervisor/arch/x86/$(CONFIG_BOARD) folder (with this file we could bypass
ENFORCE_VALIDATED_ACPI_INFO check and benifit for development). If this
file is not exist, then hypervisor/arch/x86/configs/platform_acpi_info.h
will be included as final target acpi info.
The process should work for UEFI path also, with a valid platform acpi
info file, S3/S5 should work on UEFI platform.

In this patch, only set the corresponding bit of EOI-exit bitmap for
a vcpu when a level triggered interrupt has accepted in IRR or clear the
corresponding bit of EOI-exit bitmap for a vcpu when a dege triggered interrupt
has accepted in IRR which means only update a bit of EOI-exit bitmap in a vcpu
