This patch set is against acpi-test sysfs branch,
and will duplicate several ACPI procfs functions in sysfs.

Patch 01:
add a Kconfig option to make ACPI procfs configurable.
This will be used by all the following sysfs conversion patches.

Patch 02:
add ACPI debug attribute in sysfs.
/proc/acpi/debug_layer && debug_level is deprecated by
/sys/module/acpi/parameter/debug_layer && debug_level.

Patch 03:
add ACPICA version in sysfs.
/proc/acpi/info is deprecated by /sys/firmware/acpi/version.

Wish list:

Sysfs interfaces for all the ACPI tables, like the multiple ssdts and
dynamic loaded ssdts, which are likely to be listed under
/sys/firmware/acpi/tables/...

"wakeup" attribute for ACPI wakeup devices.
        1. Try to map ACPI devices to the physical devices.
           It's not very easy, as we can not find a generic method to
           map ACPI wakeup devices to physical devices. So I have to
           divide them into several groups, e.g. PCI, legacy serial,
           legacy PS2, etc. And verify which group the ACPI device 
           belongs to.
        2. add "wakeup" properly to /sys/device/(not ACPI)/...
           I'll investigate the possibility of integrating this one into
           /sys/device/.../power/wakeup.
        3. consolidate all wakeup devices in one place for convenience.
           E.g. /sys/power/wakeup/, symbolic links with useful names.
           (note that links here are from "real" devices node in sysfs,
           so it's a generic interface for systems both w/ and w/o ACPI)
        4. remove /proc/acpi/wakeup,
           since it's replaced by /sys/power/wakeup/...
