PM / Hibernate: Add new sysfs attribute for controlling reserved memory

The attached patch adds a new knob, /sys/power/reserved_size, allowing you to
set the size of memory (in bytes) to be reserved for device drivers'
hibernation callbacks while counting the number of memory pages to allocate.

Please check if you can set it to such a number that hibernation will always
succeed on your machine.
