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

Browse Source 
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.

Enables a workaround for IFC erratum A003399. It is only
requred during NOR boot.
CONFIG_A008044_WORKAROUND
Enables a workaround for T1040/T1042 erratum A008044. It is only
requred during NAND boot and valid for Rev 1.0 SoC revision
CONFIG_SYS_FSL_CORENET_SNOOPVEC_COREONLY
This is the value to write into CCSR offset 0x18600
