506df9dc58 treewide: rework linker symbol declarations in sections header
1. Convert all linker symbols to char[] type so that we can get the
   corresponding address by calling array name 'var' or its address
   '&var'. In this way, we can avoid some potential issues[1].
2. Remove unused symbol '_TEXT_BASE'. It has been abandoned and has
   not been referenced by any source code.
3. Move '__data_end' to the arch x86's own sections header as it's
   only used by x86 arch.
4. Remove some duplicate declared linker symbols. Now we use the
   standard header file to declare them.

a077ac13d0 Kconfigs: Correct default of "0" on hex type entries

incorrect default. Fix one instance (in two configs) of a default of "0"

OpenOCD is one of the most popular environment for providing debug
