arm64: Create sections.h

Browse Source 
Each time new section markers are added, kernel/vmlinux.ld.S is updated,
and new extern char __start_foo[] definitions are scattered through the
tree.

Create asm/include/sections.h to collect these definitions (and include
the existing asm-generic version).
