bis_factory: Use hardware default NAND partition sizes

Browse source 
Sets the total space of user and system partitions to their hardware defaults.
Furthermore, return the total space as free space for the user partition to prevent it from reaching zero.
Some games like Bioshock 2 check for the available free space prior to save creation, and we should not be limited by arbitrary limits.
