[U-Boot] tlb15_entry is set wrong in the 4K code when the MPC8572DS boots from nand flash

[Y fan]

Hello,

The memory of the MPC8572DS can't be read correctly after the setup of the
tlb1_entry in the 4K boot code.

And also in the create_init_ram code, the tlb1_entry15&14 are set to be in
the address space 0 which are supposed to be used in the address space 1.
There seems somthing wrong with the writing of the TLB entry. But I don't
know why. Do anyone know the reason?

Thank you very much.
