Tracing through the code, no current PMU sleep notifier can abort sleep.
Since no new PMU sleep notifiers should be added, this patch simplifies the
code and removes the ability to abort sleep.

This removes the time suspend/restore code that was done through
a PMU notifier in arch/platforms/powermac/time.c.

Instead, introduce arch/powerpc/sysdev/timer.c which creates a sys
device and handles time of day suspend/resume through that.

This should probably be replaced by using the generic RTC framework
but for now it gets rid of the arcane powermac specific hack.

This patch updates booting-without-of.txt to describe version 17 of
the flattened device tree format.  Version 17 is a small, backwards
compatible change from version 16, adding an extra field giving the
size of the device tree's structure block.  At this time, the kernel
has no use for the extra information, however its presence can make
life easier for bootloaders or other software manipulating the tree.

In addition this patch adds information on the size_dt_strings field
of the device tree header, present since version 3 of the flattened
tree format, but omitted from the documentation.  It also makes
changes to consistently refer to versions 16 and 17 as versions 16 and
17 in decimal, rather than version 0x10 which was occasionally used
for version 16 previously.

Finally, we also add the new field to the definition of the device
tree header structure in prom.h
