* Naming convention for AML interpreter execution routines.

* The routines that begin execution of AML opcodes are named with a common

*
* AcpiExOpcode_xA_yT_zR

* Where:
*
* xA - ARGUMENTS: The number of arguments (input operands) that are
* required for this opcode type (1 through 6 args).
* yT - TARGETS: The number of targets (output operands) that are required
* for this opcode type (0, 1, or 2 targets).
* zR - RETURN VALUE: Indicates whether this opcode type returns a value
* as the function return (0 or 1).
*
* The AcpiExOpcode* functions are called via the Dispatcher component with
