[PATCH 1/4] common/board_f: remove XTRN_DECLARE_GLOBAL_DATA_PTR dead code

[Ovidiu Panait]

The XTRN_DECLARE_GLOBAL_DATA_PTR declarations in ppc code are permanently
commented out, so there are no users for this macro:
  #if 1
    #define DECLARE_GLOBAL_DATA_PTR   register volatile gd_t *gd asm ("r2")
  #else
    #define XTRN_DECLARE_GLOBAL_DATA_PTR   extern
    #define DECLARE_GLOBAL_DATA_PTR     XTRN_DECLARE_GLOBAL_DATA_PTR \
                                        gd_t *gd
  #endif

Remove all references.
