Sumit Garg 4139b17037 armv8: ls1043ardb: SPL size reduction 
Using changes in this patch we were able to reduce approx 10k
size of u-boot-spl.bin image. Following is breif description of
changes to reduce SPL size:
1. Changes in board/freescale/ls1043ardb/Makefile to remove
   compilation of eth.c and cpld.c in case of SPL build.
2. Changes in board/freescale/ls1043ardb/ls1043ardb.c to keep
   only ddr_init and board_early_init_f funcations in case of SPL
   build.
3. Changes in ls1043a_common.h & ls1043ardb.h to remove driver
   specific macros due to which static data was being compiled in
   case of SPL build.
4. Disable MMC driver from bieng compiled in case of SPL NAND
   build and NAND driver from bieng compiled in case of SPL MMC build.
5. Remove I2C driver support from SPL in case of LS1043ARDB.

Overview
--------
The LS1043A Development System (QDS) is a high-performance computing,
evaluation, and development platform that supports the QorIQ LS1043A
LayerScape Architecture processor. The LS1043AQDS provides SW development
platform for the Freescale LS1043A processor series, with a complete
debugging environment.
