PM/Hibernate: Move NVS routines into a seperate file (v2).
The *_nvs_* routines in swsusp.c make use of the io*map()
functions, which are only provided for HAS_IOMEM, thus
breaking compilation if HAS_IOMEM is not set. Fix this
by moving the *_nvs_* routines into hibernate_nvs.c, which
is only compiled if HAS_IOMEM is set.
[rjw: Change the name of the new file to hibernate_nvs.c, add the
license line to the header comment.]
