[PATCH v14 02/92] vmlinux.lds.h: move BOUNDED_SECTION_* macros to reuse later

[Jim Cromie]

Move BOUNDED_SECTION_* macros to a new helper file:
include/asm-generic/bounded_sections.lds.h
and include it back into vmlinux.lds.h

This allows its reuse later to fix a future problem with modules
failing to keep dyndbg sections in some circumstances.

NB: this ignores a checkpatch warning, because new file is covered by
GENERIC INCLUDE/ASM HEADER FILES
