/// The Differentiated System Description Table (DSDT) is part of the system fixed description.
/// The DSDT is comprised of a system description table header followed by data in Definition Block format. See Section 5.2.11 for a description of Definition Blocks.
/// During initialization, OSPM finds the pointer to the DSDT in the Fixed ACPI Description Table (using the FADT's `dsdt` or `x_dsdt` fields) and then loads the DSDT to create the ACPI Namespace.
