x86/asm: Further improve segment.h readability
- extend/clarify explanations where necessary
- move comments from macro values to before the macro, to
make them more consistent, and to reduce preprocessor overhead
- sort GDT index and selector values likewise by number
- use consistent, modern kernel coding style across the file
- capitalize consistently
- use consistent vertical spacing
- remove the unused get_limit() method (noticed by Andy Lutomirski)
No change in code (verified with objdump -d):
