ACPI: introduce module parameter acpi.aml_debug_output
Introduce module parameter acpi.aml_debug_output. With acpi.aml_debug_output set, we can get AML debug object output (Store (AAA, Debug)), even with CONFIG_ACPI_DEBUG cleared. Together with the runtime custom method mechanism, we can debug AML code problems without rebuilding the kernel.
