Now that device_create() has been audited, rename things back to the
original call to be sane.

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

Manual fixup of:

	arch/powerpc/Kconfig

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.

Commit c9f6d3d5c6d4f4cd3a53549a69c92951180e2a76 ("[POWERPC] adb: Replace
sleep notifier with platform driver suspend/resume hooks") introduced
compile errors on m68k because <linux/platform_device.h> is not
explicitly included.  On powerpc, it's pulled in through <asm/prom.h>.
