common/board_f: Initialized global data for generic board
Some platforms (tested on mpc85xx, mpc86xx) use global data before calling function baord_inti_f(). The data should not be cleared later. Any arch which uses global data in generic board board_init_f() should define CONFIG_SYS_GENERIC_GLOBAL_DATA.
