arm: fix __efi_runtime_rel_start/end definitions
__efi_runtime_rel_start/end are defined as c variables for arm7 only in
order to force the compiler emit relative references. However, defining
those within a section definition will do the same thing since [0].
On top of that the v8 linker scripts define it as a symbol.
So let's remove the special sections from the linker scripts, the
variable definitions from sections.c and define them as a symbols within
the correct section.
[0] binutils commit 6b3b0ab89663 ("Make linker assigned symbol dynamic only for shared object")
