DynamicTablesPkg: Add support to specify FADT minor revision
The CM_STD_OBJ_ACPI_TABLE_INFO.AcpiTableRevision can be used to specify
the major revision number of the ACPI table that the generator must use.
Although most ACPI tables only have a major revision number, the FADT
table additionally has a minor revision number.
The FADT generator currently defaults to setting the latest supported
ACPI revision for the FADT table i.e. ACPI 6.4. This means that the minor
revision for the FADT table is always set to 4 and there is no provision
for a user to specify the minor revision to be selected.
Therefore, update CM_STD_OBJ_ACPI_TABLE_INFO to introduce a new field
MinorRevision which can be used to specify the minor revision for an
ACPI table. Also update the FADT generator to validate the supported
FADT revisions ans use the specified minor revision for the FADT table
if supported. If an unsupported minor revision is specified the FADT
generator defaults to the latest supported minor revision.
Since the CM_STD_OBJ_ACPI_TABLE_INFO.MinorRevision field is added to
the end of the structure, it should not break existing platform code.
