Input: add appleir USB driver
This driver was originally written by James McKenzie, updated by
Greg Kroah-Hartman, further updated by myself, with suspend support
added.
More recent versions of the IR receiver are also supported through
a patch by Alex Karpenko.
Tested on a MacbookAir1,1

Add HID_QUIRK_HIDDEV_FORCE and HID_QUIRK_NO_IGNORE
Add two quirks to make it possible for usbhid module options to
override whether a device is ignored (HID_QUIRK_NO_IGNORE) and
whether to connect a hiddev device (HID_QUIRK_HIDDEV_FORCE).
Passing HID_QUIRK_NO_IGNORE for your device means that it will
not be ignored by the HID layer, even if present in a blacklist.
HID_QUIRK_HIDDEV_FORCE will force the creation of a hiddev for that
device, making it accessible from user-space.
Tested with an Apple IR Receiver, switching it from using appleir
to using lirc's macmini driver.

+Apple IR receiver Driver (appleir)
+----------------------------------
+ Copyright (C) 2009 Bastien Nocera <hadess@hadess.net>
+
+The appleir driver is a kernel input driver to handle Apple's IR
+receivers (and associated remotes) in the kernel.
+
+The driver is an input driver which only handles "official" remotes
+as built and sold by Apple.
+
+Authors
+-------
+
+James McKenzie (original driver)
+Alex Karpenko (05ac:8242 support)
+Greg Kroah-Hartman (cleanups and original submission)
+Bastien Nocera (further cleanups and suspend support)
+
+Supported hardware
+------------------
+
+- All Apple laptops and desktops from 2005 onwards, except:
+ - the unibody Macbook (2009)
+ - Mac Pro (all versions)
+- Apple TV (all revisions)
+
+The remote will only support the 6 buttons of the original remotes
+as sold by Apple. See the next section if you want to use other remotes
+or want to use lirc with the device instead of the kernel driver.
+
+Using lirc (native) instead of the kernel driver
+------------------------------------------------
+
+First, you will need to disable the kernel driver for the receiver.
+
+This can be achieved by passing quirks to the usbhid driver.
+The quirk line would be:
+usbhid.quirks=0x05ac:0x8242:0x40000010
+
+With 0x05ac being the vendor ID (Apple, you shouldn't need to change this)
+With 0x8242 being the product ID (check the output of lsusb for your hardware)
+And 0x10 being "HID_QUIRK_HIDDEV_FORCE" and 0x40000000 being "HID_QUIRK_NO_IGNORE"
+
+This should force the creation of a hiddev device for the receiver, and
+make it usable under lirc.
