ACPI: Register EC io ports in /proc/ioports

Formerly these have been exposed through /proc/..
Better register them where all IO ports should get registered
and scream loud if someone else claims to use them.

EC data and command port typically should show up like this
then:
...
  0060-0060 : keyboard
  0062-0062 : EC data
  0064-0064 : keyboard
  0066-0066 : EC command
  0070-0071 : rtc0
...

ACPI: Provide /sys/kernel/debug//ec/ec0/io for binary access to the EC

A userspace app to easily read/write the EC can be found here:

Multiple ECs are not supported, but shouldn't be hard to add as soon

ACPI: Provide /sys/kernel/debug/ec/...

This patch provides the same information through debugfs, which previously was
provided through /proc/acpi/embedded_controller/*/info

This is the gpe the EC is connected to and whether the global lock
gets used.
The io ports used are added to /proc/ioports in another patch.
Beside the fact that /proc/acpi is deprecated for quite some time,
this info is not needed for applications and thus can be moved
to debugfs instead of a public interface like /sys.

compal-laptop: add JHL90, battery & hwmon interface

The driver now supports the Compal JHL90 (which I use) and it has some
added features.  The biggest novelties are a battery interface
(power_supply) and a temperature and fan control interface (hmwon).  It
also adds a power-off feature to the backlight subsystem and it exports a
few files that can enable/disable wake_on_XXX events.

Much of the original code of the old features is still there, but I've
changed some names to keep the naming more coherent with the added
functionalities.  (Sorry for the huge patch)

Some technical stuff about the new driver:

First of all, I'm not sure if the extra features also work on the other
Compal boards.  Currently they only get enabled if the DMI data indicates
you are on a JHL90 board.

Secondly, I've noticed a quirk in my fan controller.  I have to re-send
the wanted pwm-level to the controller every so often.  If I don't do
this, the fanspeed will slowly rise until after a couple of minutes it's
at full speed.  (Note that every normal userland application will probably
update the pwm-level every so often anyway, based on temperature readings,
so this might not be an issue in practice) If this turns out to be a
problem with all the controllers, maybe we should implement a kernel timer
and have the driver re-send the pwm level every XX seconds to make this
transparent to userspace?  (However, I couldn't immediately find a way to
do this cleanly.)

Additional information can be found in the source comments.

I made this change because the documents in platform.c shows that:

x86 platform driver: intelligent power sharing driver

Intel Core i3/5 platforms with integrated graphics support both CPU and
GPU turbo mode.  CPU turbo mode is opportunistic: the CPU will use any
available power to increase core frequencies if thermal headroom is
available.  The GPU side is more manual however; the graphics driver
must monitor GPU power and temperature and coordinate with a core
thermal driver to take advantage of available thermal and power headroom
in the package.

The intelligent power sharing (IPS) driver is intended to coordinate
this activity by monitoring MCP (multi-chip package) temperature and
power, allowing the CPU and/or GPU to increase their power consumption,
and thus performance, when possible.  The goal is to maximize
performance within a given platform's TDP (thermal design point).

- WMI query command can have arbitrary input sized params
- WMI query command can have specific output sized params (0, 4, 128,..) byte

x86 platform drivers: hp-wmi fix buffer size depending on ACPI version

Depending on ACPI version (1.0 -> 32 bit) an integer could be
32 or 64 bit long. _WED internal concatenates two integers and
the return value will be 8 byte (2* 32 bit) or 16 byte (2* 64 bit)
long, depending on the ACPI version.

Also the data send with the WMI event is defined to be splitted into:
  - Event ID -> 4 bytes
  - Event Data -> 4 bytes

This gets messed up with new ACPI versions.
But it's a HP BIOS bug that may get fixed in the future
-> Support both, 16 and 8 byte _WED buffers.

Also the wrong assumption that from the event data sent, only the
first byte is relevant got cleaned up that it fits event_id/event_data

Merge branch 'next' into for-linus

Input: adp5588-keypad - fix NULL dereference in adp5588_gpio_add()

The kpad structure is assigned to i2c client via i2s_set_clientdata()
at the end of adp5588_probe(), but in adp5588_gpio_add() we tried to
access it (via dev_get_drvdata! which is not nice at all) causing an
oops.

Let's pass pointer to kpad directly into adp5588_gpio_add() and
adp5588_gpio_remove() to avoid accessing driver data before it is
set up.

Also split out building of gpiomap into a separate function to
clear the logic.
