The patch adds support for fan control button on Ideapad Z580. This is
the same button as on Z570, but it raises different bit in
VPCCMD_R_SPECIAL_BUTTONS. Also add message to dmesg when unknown button
press detected, it will help adding support for new special buttons.

The second argument of ACPI driver .remove() operation is only used
by the ACPI processor driver and the value passed to that driver
through it is always available from the given struct acpi_device
object's removal_type field. For this reason, the second ACPI driver
.remove() argument is in fact useless, so drop it.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

The patch adds support for Lenovo IdeaPad Z570 laptop. It makes all special
keys working, adds possibility to control fan like Windows does, controls
Touchpad Disabled LED, toggles touchpad state via keyboard controller and
corrects touchpad behavior on resume from suspend. It is new, modified
version of patch. Now it does not depend on psmouse and does not need patching
of input subsystem.

We only initialize the high bits of "cfg". It probably doesn't cause
a problem given that this is platform specific code and doesn't have to
worry about endianness etc. But it's sort of messy.

Novo key is the Lenovo define key on every ideapads, which has two
definition. Long press and short click. Driver will report
KEY_PROG1 on short click and KEY_PROG2 when long press.
On pre-install OS for ideapads there are application waiting for
the event and there is no such application for Linux yet, so I
think to report KEY_PROG is fine in anyway.
Also change the scancode from hex to decimal because they are
related to vpc bit in notify function which is in decimal.

For some ideapad when push Fn+F3, hardware generates Super-P keys, those key
will not be enabled by this patch.
Thanks for Dave Hansen report the problem. If CONFIG_INPUT_SPARSEKMAP is not
set, when building, you will have error message:
ERROR: "sparse_keymap_setup" [drivers/platform/x86/ideapad-laptop.ko] undefined!
ERROR: "sparse_keymap_free" [drivers/platform/x86/ideapad-laptop.ko] undefined!

To select INPUT_SPARSEKMAP solve this issue.

Add new module parameter that force module not to register bluetooth rfkill.
There is report that saying using this bluetooth rfkill to enable/disable
bluetooth will let bluetooth device initial failed when enable on Lenovo
ideapad S12. Fortunately there is another rfkill registered by bluetooth
driver for S12 and user can shutdown the bluetooth by either bluetooth driver
or HW RF switch.
For dual OS user, it may have some trouble that using Linux after turning off
bluetooth with another OS if we do not register bluetooth rfkill at all. So
we will force bluetooth enable when no_bt_rfkill=1.
