[U-Boot] [PATCH v2] armv8: fsl-layerscape: Fix early MMU table for nand boot

[York Sun]

The early MMU table doesn't enable all addresses. Unused addresses
are marked as invalid, as introduced by commit 9979922. An entry
was missing for NAND flash space, causing nand boot failure.

Changes in v2:
  Reduce the IFC mapped for early MMU, up to NOR flash base to
  avoid conflict
  Tested on LS2085AQDS
