ACPI: support customizing ACPI control methods at runtime
Introduce a new debugfs I/F (/sys/kernel/debug/acpi/custom_method) for ACPI,
which can be used to customize the ACPI control methods at runtime.
We can use this to debug the AML code level bugs instead of overriding the
whole DSDT table, without rebuilding/rebooting kernel any more.
Detailed description about how to use this debugfs I/F is stated in
Documentation/acpi/method-customizing.txt
