Using changes in this patch we were able to reduce approx 4k size of u-boot-spl.bin image. Following is breif description of changes to reduce SPL size:

1. Compile-off mp.c and libfdt.c in case of SPL build.
2. Keep MMU and DCACHE specific variable and functions under CONFIG_SYS_DCACHE_OFF macro.
3. Compile-off IFC specific funtion call "init_early_memctl_regs" in case of SPL build.

Dependent on ls1088 base SD boot target. Also dependent on ls1088 QPSI secure boot target.

I don't agree D-cache should be off for SPL boot. Please find other way to reduce SPL image size.
