[U-Boot] [PATCH v5 1/3] armv8:fsl-layerscape: Consolidate registers space defination for CCI-400 bus

CoreLink Cache Coherent Interconnect (CCI) is ARM BUS which
provides full cache coherency between two clusters of multi-core
CPUs and I/O coherency for devices and I/O masters.
This patch add new CONFIG defination "SYS_FSL_HAS_CCI400" and
moves existing register space definaton of CCI-400 bus
from immap_lsch2 to fsl_immap, so that it can be used
for both chasis 2 and chasis 3.
"CONFIG_SYS_CCI400_ADDR" is depricated and new SYS_CCI400_OFFSET
is introduced in Kconfig
