ipq8064: add DRAM initialization code
Read two blobs from CBFS: cdt.mbn (memory configuration descriptor)
and ddr.mbn (actual memory initialization code).
Pointer to CDT which starts right above the MBN header is passed to
the memory initialization routine. Zero return value means memory
initialization succeeded.
BRANCH=storm
BUG=chrome-os-partner:34161
TEST=with upcoming patches memory initialization succeeds.
