From: Colin Ian King <colin.king@canonical.com>

Enable the kernel ACPI driver debugger to help debug ACPICA at
runtime and also add the acpidbg userspace debugging tool in the
linux-tools package.  A user with root privilege can attach the
ACPI kernel debugger using the acpidbg tool and interactively
debug the ACPI objects, such as single stepping control methods
and printing ACPI object using the kernel debug sysfs file
/sys/kernel/debug/acpi/acpidbg.  This is a useful tool for the
HWE folk to debug and resolve gnarly ACPI issues.

For the moment, enable this for x86 architectures only. Once I
get access to a fully functional ARM64 platform with ACPI support
and test this I will enable it for this too.

Applied to unstable/master after running updateconfigs with the config
changes. Thanks!
