ASUS F2A85-M: romstage.c: Set RAM voltage for non 1.5 Volt case

Currently the if statement

if (!byte)
        	do_smbus_write_byte(0xb20, 0x15, 0x3, byte);

only gets executed if `byte == 0x0`, that means only in the
    default case where RAM voltage is 1.5 Volts. But the RAM voltage
    should be changed when configured for the non-default case.

So change the predicament to alter the RAM voltage for the
    non-default cases.
