[PATCH resend 4/5] mpc8xxx_spi: always use 8-bit characters, don't read or write garbage

There are a few problems with the current driver. First, it unconditionally reads from dout/writes to din whether or not those pointers are NULL. So for example a simple "sf probe" ends up writing four bytes at address 0: => md.l 0x0 8 : 45454545 45454545 05050505 05050505
