platform/x86: asus-wmi: Move acpi_backlight=vendor quirks to ACPI video_detect.c

Remove the asus-wmi quirk_entry.wmi_backlight_power quirk-flag, which
called acpi_video_set_dmi_backlight_type(acpi_backlight_vendor) and replace
it with acpi/video_detect.c video_detect_dmi_table[] entries using the
video_detect_force_vendor callback.

acpi_video_set_dmi_backlight_type() is troublesome because it may end up
getting called after other backlight drivers have already called
acpi_video_get_backlight_type() resulting in the other drivers
already being registered even though they should not.

Note no entries are dropped from the dmi_system_id table in asus-nb-wmi.c.
This is because the entries using the removed wmi_backlight_power flag
also use other model specific quirks from the asus-wmi quirk_entry struct.
So the quirk_asus_x55u struct and the entries pointing to it cannot be
dropped.

ACPI: Clean up inclusions of ACPI header files

Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and
<acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h>
inclusions and remove some inclusions of those files that aren't
necessary.

First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>
should not be included directly from any files that are built for
CONFIG_ACPI unset, because that generally leads to build warnings about
undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set,
<linux/acpi.h> includes those files and for CONFIG_ACPI unset it
provides stub ACPI symbols to be used in that case.

Second, there are ordering dependencies between those files that always
have to be met. Namely, it is required that <acpi/acpi_bus.h> be included
prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the
latter depends on are always there. And <acpi/acpi.h> which provides
basic ACPICA type declarations should always be included prior to any other
ACPI headers in CONFIG_ACPI builds. That also is taken care of including
<linux/acpi.h> as appropriate.

asus-wmi: store backlight power status for AIO machine

Due to some implementation reasons, ASUS ET2012 All-in-One machines
can't report the correct backlight power status, it will always return
1. To track the backlight power status correctly, we have to store the
status by ourselves.

BTW, by the BIOS design, the backlight power will be turn on/off
sequently, no matter what the value of the parameter will be.
More over, the brightness adjustment command will turn on the backlight
power. Those behaviors will make us fail to track the backlight power
status.
For example, While we are trying to turn on the backlight power,
we will send out the brightness adjustment command and then trying to
figure out if we have to turn on the backlight power, then send out
the command. But, the real case is that, the backlight power turns on
while sending the brightness adjustment command, and then we send out
the command to turn on the backlight power, it actually will turn off
the backlight power and the backlight power status we recorded becomes
wrong. So, we have to seperate these two commands by a if statement.

asus-wmi: add scalar board brightness adj. support

Some ASUS ET2012E/I All-in-One machines that use a scalar board
to control the brightness, and they only accept brightness up and down
command. So, I introduced a get_scalar_command() function to pass the
command to the scalar board through WMI.

Besides, we have to store the brightness value locally, for we need the
old value to know the brightness value is increasing or decreasing.

BTW, since there is no way to retrieve the actual brightness(it would be
a fixed value), and the max brightness value would be fixed to 1, so we
have to keep passing the brightness up/down command when we reached the
max brightness value or 0.

eeepc-wmi: Add support for T101MT Home/Express Gate key

This key is different than other hotkeys, having seperate scan
codes for press, release, and hold, so it requires some special
filtering. Press and release events are passed on, and hold events
are ignored since sparse-keymap does not support hardware
autorepeat.

Note that "Home" in the context of this button doesn't mean the
same thing as the usual Home key, and it really isn't clear at
all what is meant by "Home". The manufacurer's description of the
button indicates that it should launch some sort of touch screen
settings interface on short press and apply a desktop rotation on
long press.

New Asus notebooks are using a WMI device similar to
the one used in Eee PCs. Since we don't want to load

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.
