ACPI: turn off all debug output by default
When CONFIG_ACPI_DEBUG=y, the default acpi_dbg_layer and acpi_dbg_level values built into the ACPI CA have some debug output enabled. We'd rather be quiet unless the user actually specified the acpi.debug_level argument. This enables distros to ship with CONFIG_ACPI_DEBUG=y without inundating users with debug output.
