This patch enables the following initialization order for the new table
loading mode (which is enabled by setting
acpi_gbl_parse_table_as_term_list to TRUE):
1. Install default region handlers (SystemMemory, SystemIo, PciConfig,
EmbeddedControl via ECDT) without evaluating _REG;
2. Load the table and execute the module level AML opcodes instantly.
