In preparation for adding --orphan-handling=warn, refactor the linker
script header includes, and extract common macros.

Enabling CONFIG_GCOV_PROFILE_ALL=y causes linker errors on ARM:
`.text.exit' referenced in section `.ARM.exidx.text.exit':
defined in discarded section `.text.exit'
`.text.exit' referenced in section `.fini_array.00100':
defined in discarded section `.text.exit'
And related errors on NDS32:
`.text.exit' referenced in section `.dtors.65435':
defined in discarded section `.text.exit'
The gcov compiler flags cause certain compiler versions to generate
additional destructor-related sections that are not yet handled by the
linker script, resulting in references between discarded and
non-discarded sections.
Since destructors are not used in the Linux kernel, fix this by
discarding these additional sections.

VMLINUX_SYMBOL() is no-op unless CONFIG_HAVE_UNDERSCORE_SYMBOL_PREFIX
is defined. It has ever been selected only by BLACKFIN and METAG.
VMLINUX_SYMBOL() is unneeded for ARM-specific code.

Let's put the TCM stuff in the __init section directly. No need for
a separately freed memory area.
Remove redundant linker sections, as well as comments that were more
confusing than no comments at all. Finally make it XIP compatible by
using LOAD_OFFSET in the section LMA specification.

This is a plain move with identical results, and therefore
still broken in the XIP case.

Move common entries to vmlinux.lds.h and leave XIP and non-XIP entries
in their respective file. The ARM_NOMMU_KEEP() and ARM_NOMMU_DISCARD()
macros are added to be usable within the definition of ARM_DISCARD macro.

Lots of duplications between vmlinux.lds.S and vmlinux-xip.lds.S.
This may lead to one file being updated but not the other. For example,
SOFTIRQENTRY_TEXT and HYPERVISOR_TEXT were missing from the XIP version.
This creates vmlinux.lds.h where a bunch of common defines are moved.
