powerpc/mpc85xx:Put errata number for T104x NAND boot issue

When device is configured to load RCW from NAND flash IFC_A[16:31] are driven
low after RCW loading. Hence Devices connected on IFC_CS[1:7] and using
IFC_A[16:31] lines are not accessible.

Workaround is already in-place.
Put the errata number to adhere errata handling framework.
