rename the macro since MAX_PCPU_NUM could be parsed from board file and
it is not a configurable item anymore.

The default PCI mmcfg base is stored in ACPI MCFG table, when
CONFIG_ACPI_PARSE_ENABLED is set, acpi_fixup() function will
parse and fix up the platform mmcfg base in ACRN boot stage;
when it is not set, platform mmcfg base will be initialized to
DEFAULT_PCI_MMCFG_BASE which generated by acrn-config tool;
Please note we will not support platform which has multiple PCI
segment groups.

Statically define the per vm RSDP/XSDT/MADT ACPI template tables in vacpi.c,
RSDP/XSDT tables are copied to guest physical memory after checksum is
calculated. For MADT table, first fix up process id/lapic id in its lapic
subtable, then the MADT table's checksum is calculated before it is copies to
guest physical memory.
Add 8-bit checksum function in util.h

Currently ACPI related defines/structs are scattered across multiple C
source files, move them into acpi.h so that they can be shared and used by
vacpi code (to be added in subsequent commits).

Previously we use Kconfig of DMAR_PARSE_ENABLED to choose pre-defined DMAR info
or parse it at runtime, at the same time we use MACRO of CONFIG_CONSTANT_ACPI
to decide whether parse PM related ACPI info at runtime. This looks redundant
so use a unified ACPI_PARSE_ENABLED Kconfig to replace them.

Previously ACPI PM1A register info was hardcoded to 0 in HV for generic boards,
but SOS still can know the real PM1A info so the system would hang if user
trigger S3 in SOS. Enabling PM1A register info fixup will let HV be able to
intercept the operation on PM1A and then make basic function of S3 work for
all boards;

IOAPIC info, specifically ID, is needed to map the IOAPIC to
corresponding DMAR. DMAR table in ACPI has a field that has IOAPIC
ID, that matches the info provided in MADT. Both (IOAPIC info from
MADT and from DMAR) is needed for remapping IOAPIC interrupts.

In the hypervisor, physical cpu id is defined as "int" or "uint32_t"
type in the hypervisor. So there are some sign conversion issues
about physical cpu id (pcpu_id) reported by static analysis tool.
Sign conversion violates the rules of MISRA C:2012.
In this patch, define physical cpu id as "uint16_t" type for all
modules in the hypervisor and change related codes. The valid
range of pcpu_id is 0~65534, INVALID_PCPU_ID is defined to the
invalid pcpu_id for error detection, BROADCAST_PCPU_ID is
broadcast pcpu_id used to notify all valid pcpu.
The type of pcpu_id in the struct vcpu and vcpu_id is "int" type,
this will be fixed in another patch.
V1-->V2:
* Change the type of pcpu_id from uint32_t to uint16_t;
* Define INVALID_PCPU_ID for error detection;
* Define BROADCAST_PCPU_ID to notify all valid pcpu.
V2-->V3:
* Update comments for INVALID_PCPU_ID and BROADCAST_PCPU_ID;
* Update addtional pcpu_id;
* Convert hexadecimals to unsigned to meet the type of pcpu_id;
* Clean up for MIN_PCPU_ID and MAX_PCPU_ID, they will be
defined by configuration.
Note: fix bug in the init_lapic(), the pcpu_id shall be less than 8,
this is constraint by implement in the init_lapic().
