device_create() is race-prone, so use the race-free
device_create_drvdata() instead as device_create() is going away.

This makes two changes:
* As noted by Akinobu Mita in patch
b1fceac2b9, alloc_bootmem never returns NULL
and always returns a zeroed region of memory. Thus the error checking code
and memset after the call to alloc_bootmem are not necessary.
* The old error handling code consisted of setting a global variable to
NULL and returning an error code, which could cause previously allocated
resources never to be freed. The patch adds calls to appropriate resource
deallocation functions.

This contains the following cleanups:
- make the following needlessly global code static:
- adb.c: adb_controller
- adb.c: adb_init()
- adbhid.c: adb_to_linux_keycodes[] (also make it const)
- via-pmu68k.c: backlight_level
- via-pmu68k.c: backlight_enabled
- remove the following unused code:
- via-pmu68k.c: sleep_notifier_list

Put explicit lock_kernel() calls in adb_open(). The fact that
adb_release() already has them suggests this is necessary.

of_node_put is needed before discarding a value received from
of_find_node_by_name, eg in error handling code.

If the adbhid module parameter restore_capslock_events is used,
pressing the power button may confuse the capslock state. This is
because the power button release scancode (0xff) is sometimes the same
as the capslock press/release scancode.
This fix adds yet another flag to track the state of the power button
so that it works independently of capslock.

If the adbhid module parameter restore_capslock_events is used,
sometimes capslock will get stuck down after resuming.
My fix is to remember the capslock state before suspend and then
ignore the first 'caps lock key down' message after resume if the
capslock LED was on before suspending.

Create /sys/bus/of_platform/devices/*/modalias file to allow autoloading
of modules. Modalias files are already present for many other bus types.
This adds also a newline to the devspec files.
Also create a devspec file for mac-io devices. They were created as a
side effect. Use correct buffer size for mac-io modalias buffer.
Tested on iBook1 and Efika.
