Introduce a new driver for Asus Notebooks shipped with
a WMI device instead of the old ACPI device. The WMI
device is almost the same as the one present in Eee PC,
but the event guid and the keymap are different.

The keymap comes from asus-laptop module.

On Asus notebooks, when you call the WMI device, you always
need a 64bit buffer, even if you only want to get the state
of a device (tested on a G73).

This is tricky, new WMI aware notebooks seems to use
0x53545344 while Eee PCs are using 0x53544344. But there
is no way to know if there is an Eee PC in that wild that is
using 0x53545344 or a notebook using 0x53544344. So the
driver try to guess the available DSTS method ... But most Eee PCs
never return 0xFFFFFFFE when a method is not available, they return
0 instead (and that's useless).

So, first, try 0x53544344 then 0x53545344. We will find
a better way when we got more data.

This patch create a single function to call the
WMI methods. This function handle inexistent methods (when
implemented by the WMI devices, and this is not the case on
Eee PCs), ACPI errors, etc..

Also pack struct bios_arg, and make sure that we always send
a 64bit buffer when calling a WMI method, because this is
needed on Asus notebooks.

New Asus notebooks are using a WMI device similar to
the one used in Eee PCs. Since we don't want to load
eeepc-wmi module on Asus notebooks, and we want to
keep the eeepc-wmi module for backward compatibility,
this patch introduce a new module, named asus-wmi, that
will be used by eeepc-wmi and the new Asus Notebook WMI
Driver.

eeepc-wmi's input device strings (device name and phys)
are kept, but rfkill and led names are changed (s/eeepc/asus/).
This should not break anything since rfkill are used by type or
index, not by name, and the eeepc::touchpad led wasn't working
correctly before 2.6.39 anyway.

Split buffersize parameter of hp_wmi_perform_query to insize and
outsize. Existing callers are changed to use the same value for insize
and outsize to avoid any regressions, with the exception of
hp_wmi_set_block where the output buffer is unused and therefore outsize
is set to 0 (this change is not seen by BIOS code).

The maximum input buffer size is kept at 4 bytes as per struct
bios_args. Some commands exist that take longer buffers, but they
haven't been implemented. The data portion of bios_args can be trivially
made dynamically allocated later when such larger buffers become needed.
