[PATCH 02/04] Driver Core: Add idle and wakeup functions

[Magnus Damm <magnus.damm@gmail.com>]

From: Magnus Damm <damm@igel.co.jp>

Add platform_device_idle() and platform_device_wakeup()
and allow architectures to implement their own versions
of these if CONFIG_HAVE_PLATFORM_IDLE_WAKEUP is set.

 Yes, this needs documentation. See [00/04] for now.
