platform/x86: asus-wmi: expose dGPU and CPU tunables for ROG

Expose various CPU and dGPU tunables that are available on many ASUS
ROG laptops. The tunables shown in sysfs will vary depending on the CPU
and dGPU vendor.

All of these variables are write only and there is no easy way to find
what the defaults are. In general they seem to default to the max value
the vendor sets for the CPU and dGPU package - this is not the same as
the min/max writable value. Values written to these variables that are
beyond the capabilities of the CPU are ignored by the laptop.

platform/x86: asus: Rename "fan mode" to "fan boost mode"

The Asus WMI spec indicates that the function being controlled here
is called "Fan Boost Mode". The user-facing documentation also calls it
this.

The spec uses the term "fan mode" is used to refer to other things,
including functionality expected to appear on future products.
We missed this before as we are not dealing with the most readable of
specs, and didn't forsee any confusion around shortening the name.

Rename "fan mode" to "fan boost mode" to improve consistency with the
spec and to avoid a future naming conflict.

There is no interface breakage here since this has yet to be included
in an official kernel release. I also updated the kernel version listed
under ABI accordingly.

platform/x86: asus-wmi: Switch fan boost mode

The WMI exposes a write-only device ID where up to three fan modes can be
switched on some laptops (TUF Gaming FX505GM). There is a hotkey
combination Fn-F5 that does have a fan icon, which is designed to toggle
between fan modes. The DSTS of the device ID returns information about the
presence of this capability and the presence of each of the two additional
fan modes as a bitmask (0x01 - overboost present, 0x02 - silent present)
[1].

Add a SysFS entry that reads the last written value and updates value in
WMI on write and a hotkey handler that toggles the modes taking into
account their availability according to DSTS.

Modes:
* 0x00 - normal or balanced,
* 0x01 - overboost, increased fan RPM,
* 0x02 - silent, decreased fan RPM

asus-wmi: enable resume on lid open

According to the ASUS WMI spec., to enable resume on lid open should
use the device ID(0x00120032), but it doesn't work indeed.

After discussing with ASUS' BIOS engineer, they say wake on lid open
doesn't have a uniq device ID(0x00120032) in the BIOS. It shares the same
device ID with deep S3(0x00120031), and the deep S3(resume on lid open)
is disable by default.

Adding this option in asus wmi sysfs
/sys/devices/platform/<platform>/lid_resume
so that userspace apps can enable/disable this feature by themselves.

eeepc-wmi: asus generic asus-wmi.ko module

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.
