MISRA C requires specified bounds for arrays declaration, previous declaration
of platform_clos_array in board.h does not meet the requirement.

The DMAR info is board specific so move the structure definition to board.c.
As a configruation file, the whole board.c could be generated by acrn-config
tool for each board.
Please note we only provide DMAR info MACROs for nuc7i7dnb board. For other
boards, ACPI_PARSE_ENABLED must be set to y in Kconfig to let hypervisor parse
DMAR info, or use acrn-config tool to generate DMAR info MACROs if user won't
enable ACPI parse code for FuSa consideration.
The patch also moves the function of get_dmar_info() to vtd.c, so dmar_info.c
could be removed.

MAX_PCPU_NUM is different on various BOARDs. So we move the generic

Reserve memory for hv sbuf to avoid its possible overwriting on kernel memory.
For apl-up2, move hv_log address to 0x5de00000 to avoid possible conflict with
HV_RAM which start from 0x5e000000;
For nuc6cayh, move HV_RAM_START to 0x20000000 to avoid possible conflict with
hv_log which start from 0x1fe00000;

The vCOM2 of each VM is designed for VM communication, one VM could send
command or request to another VM through this channel. The feature will
be used for system S3/S5 implementation.
On Hybird scenario, vCOM2 of pre-launched VM will connect to vCOM2 of SOS_VM;
On Industry scenario, vCOM2 of post-launched RTVM will connect to vCOM2 of
SOS_VM.

The settings of SOS VM COM1 which is used for console is board specific,
and this result in SOS VM COM2 which used for VM communication is also
board specific, so move the configure method from Kconfig to board configs
folder. The MACRO definition will be handled by acrn-config tool in future.

Currently the Px Cx supported SoCs which listed in cpu_state_tbl.c is limited,
and it is not a wise option to build a huge state table data base to support
Px/Cx for other SoCs. This patch give a alternative solution that build a board
specific cpu state table in board.c which could be auto-generated by offline
tool, then the CPU Px/Cx of customer board could be enabled;
Hypervisor will search the cpu state table in cpu_state_tbl[] first, if not
found then go check board_cpu_state_tbl. If no matched cpu state table is found
then Px/Cx will not be supported;

Previously the bootargs of SOS_VM is stored in a text file and stitched
into multiboot mods[0].string whereas the bootargs of PRE_LAUNCHED_VM is
stored in vm_configurations.c. Given the mods[].string will be used to
store Kernel image signature under hybrid mode, move the bootargs of SOS_VM
to vm configurations also to make it consistent with PRE_LAUNCHED_VM;

Previously the vm_configs[] is defined separately for sharing mode and
partition mode, but the concept of hypervisor mode will be removed. Instead
we will introduce scenario Kconfig for hypervisor to load different vm
configurations.
SDC(Software Defined Cockpit) is a typical scenario that ACRN supported
so we introduce this scenario for previously sharing mode and move its
configurations to scenarios/sdc folder. The configuration could be used
for all boards reference.

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_clos_array[PLATFORM_CLOS_NUM], it has 2 members:
1.msr_index, the MSR address of IA32_Type_MASK_n
2.clos_masky, the initial valuses
Global varible platform_clos_num is the number of IA32_Type_MASK_n,

When hypervisor start building, it will check whether BOARD specific sos_vm.h
