x86/boot/e820: Rename e820_mark_nosave_regions() to e820__register_nosave_regions()

Browse Source 
This function is a minor misnomer: it is talking about 'marking' regions
as nosave - while the hibernation API is called register_nosave_region()
and the e820_mark_nosave_regions() is a wrapper around that functionality.

So name it to be in line with the API it is derived from.

( Rename e820_mark_nvs_memory() to e820__register_nvs_regions(), for similar
  reasons. )

No change in functionality.
