PM / Hibernate: Make default image size depend on total RAM size
[ upstream commit ac5c24ec1e983313ef0015258fba6f630e54e7cf ]
The default hibernation image size is currently hard coded and euqal
to 500 MB, which is not a reasonable default on many contemporary
systems. Make it equal 2/5 of the total RAM size (this is slightly
below the maximum, i.e. 1/2 of the total RAM size, and seems to be
generally suitable).
