arm: generalize lib/bss.c into lib/sections.c

File arch/arm/lib/bss.c was initially defined for BSS only,
but is now going to also contain definitions for other
section-boundary-related symbols, so rename it for better
accuracy.

Also, remove useless 'used' attributes.

-/**
- * These two symbols are declared in a C file so that the linker
- * uses R_ARM_RELATIVE relocation, rather than the R_ARM_ABS32 one
- * it would use if the symbols were defined in the linker file.
- * Using only R_ARM_RELATIVE relocation ensures that references to
- * the symbols are correct after as well as before relocation.
- *
- * We need a 0-byte-size type for these symbols, and the compiler
- * does not allow defining objects of C type 'void'. Using an empty
- * struct is allowed by the compiler, but causes gcc versions 4.4 and
- * below to complain about aliasing. Therefore we use the next best
- * thing: zero-sized arrays, which are both 0-byte-size and exempt from
- * aliasing warnings.
