sandbox: Set up global data before board_init_f()
At present sandbox defines CONFIG_SYS_GENERIC_GLOBAL_DATA, meaning that the global_data pointer is set up in board_init_f(). If we set up and zero the global data before calling board_init_f() then we don't need to define CONFIG_SYS_GENERIC_GLOBAL_DATA. Make this change to simplify the init process.
