[U-Boot] [PATCH 7/9] ARM: socfpga: Use custom header target buffer in SPL

From: Tien Fong Chee <tien.fong.chee@intel.com>

Allocate buffers from OCRAM heap for the image headers in SPL on
Arria10, since DRAM is not available at that point. This allows
U-Boot to load the fitImage header, parse it, extract the FPGA
bitstream section from it, program the FPGA and make DRAM available.
