powerpc/mpc85xx:No NOR boot, do not compile IFC errata A003399

Browse source 
IFC errata A003399 is valid for IFC NOR boot i.e.if no on-board NOR flash or
no NOR boot, do not compile its workaround.

See Freescale App Note 4493 for more information about
this erratum.
CONFIG_A003399_NOR_WORKAROUND
Enables a workaround for IFC erratum A003399. It is only
requred during NOR boot.
CONFIG_SYS_FSL_CORENET_SNOOPVEC_COREONLY
This is the value to write into CCSR offset 0x18600
