We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to
meet kernel coding style guidelines. This issue was reported by checkpatch.
A simplified version of the semantic patch that makes this change is as
follows (http://coccinelle.lip6.fr/):
// <smpl>
@@
identifier i;
declarer name DEFINE_PCI_DEVICE_TABLE;
initializer z;
@@
- DEFINE_PCI_DEVICE_TABLE(i)
+ const struct pci_device_id i[]
= z;

The existing implementation which encodes the configuration as a binary
blob in platform data is unsatisfactory since it requires a kernel
recompile for the configuration to be changed, and it doesn't deal well
with firmware changes that move values around on the chip.
Atmel define an ASCII format for the configuration which can be exported
from their tools. This patch implements a parser for that format which
loads the configuration via the firmware loader and sends it to the MXT
chip.

Limit the number of times we allow deferred probing to attempt to add
i2c devices. This will help with some device flakiness at probe time.
For example, some touchpads and touchscreens may be in transition between
bootloader and operational mode and may appear at neither address briefly.
Adapters, however, have no limit as it depends on when the i2c adapter driver
module is loaded. The module may even be loaded manually by the user using
modprobe or insmod.
By default, set MAX_I2C_DEVICE_DEFERALS to 5.

Turns out that DMI_SYSTEM_VENDOR is actually the native vendor of each
Chromebook/box. I tested the original patch on a Pixel that -- surprise,
has Google as vendor. *facepalm*.
The only other data I can think of to probe on is Google_* in the version
string. Checking with our firmware team, all systems should have this
and nothing else than Chrome hardware should have the coreboot + Google_*
combination to date.
So, we'll switch to this. For future platforms we are going to move to
using an ACPI device to configure this instead of a DMI table (yay!),
so longer-term that will sort itself out.

Acer C720 has touchpad and light sensor connected to a separate I2C buses.
Since the designware I2C host controller driver has two instances on this
particular machine we need a way to match the correct instance. Add support
for this and then register both C720 touchpad and light sensor.
This code is based on following patch from Benson Leung:

This is a third attempt to enable these buttons. The new variable being
commit 997daa1bd9 (i.e. hp-wmi: detect
"2009 BIOS or later"). Older systems that do not have the 2009 BIOS query
method respond with a dummy value, in this case 4. Using that, we can
target a fairly narrow group of systems. i.e. old enough to not have
HPWMI_FEATURE_QUERY 0xd, but new enough to have HPWMI_BIOS_QUERY 0x9.
This group may be further limited if some systems respond with something
other than 4 to non-existant feature queries.

The T440s user guide says that when Fn-lock is not active, the *40s' F9 - F12
keys should be mapped to: control-panel, search, show-all-windows and Computer.
These keys generate the sofar unused 28 - 31 hotkey scancodes.
For the first 2 this nicely matches the icons on the keys, for the latter 2
the icons are somewhat creative, which is why I ended up looking them up in
the user manual.

This patch moves data allocated using kzalloc to managed data allocated
using devm_kzalloc and cleans now unnecessary kfrees in probe and remove
functions. The label sysfs_failed is removed as it is no longer
required. Also, linux/device.h is added to make sure the devm_*()
routine declarations are unambiguously available.

to not even try to use the wlan / bluetooth even though they work fine.
Note this patch also removes the "else priv->rfk[i] = NULL;" bit of the
rfkill initialization, it is not necessary as the priv struct is allocated
with kzalloc.
