powerpc/corenet_ds: move SATA config to board configuration

board configuration file is included before asm/config_mpc85xx.h.
however, CONFIG_FSL_SATA_V2 is defined in asm/config_mpc85xx.h.
it will never take effective in the board configuration file for
this kind of code :

 #ifdef CONFIG_FSL_SATA_V2
 ...
 #endif

To solve this problem, move CONFIG_FSL_SATA_V2 to board
configuration header file.
