x86/boot/e820: Remove e820_mark_nosave_regions() definition uglies
The e820_mark_nosave_regions definition has a number of ugly #ifdef
conditions that unnecessarily uglify both the header and the
e820.c file.
Make this function unconditional: most distro kernels have hibernation
enabled. If LTO functionality is added in the future it will be able
to eliminate unused functions without uglifying the source code.
No change in functionality.
