mt_scp: Add support to store some code in DRAM
This allows to store specific code/data in a .dram region. This
is used by mt_scp to run code off DRAM, as we plan to have more
code than what can fit in SRAM.
BRANCH=none
BUG=b:122058243
TEST=make BOARD=kukui_scp -j
objdump -x build/kukui_scp/ec.obj
=> Some code is loaded in DRAM
TEST=Load kukui_scp, icachetest works
