> The ACPI specification, version 6.3, January 2019,
> defines the Named Objects Encoding for FieldElements
> in section '20.2.5.2 Named Objects Encoding'.
> FieldElements can be one of the following:
> NamedField | ReservedField | AccessField |
> ExtendedAccessField | ConnectField
> 
> Some of these keywords are starting with an opcode,
> allowing to identify their type.
> E.g.: ReservedField := 0x00 PkgLength
> 
> This patch adds these FieldElement opcodes definitions to
> the list of AML Opcode definitions.
