3rdparty/blobs: Update submodule, SNB improvements
The sandybridge systemagent-r6 blob is modified:
- To be more flexible about the location of the stack w.r.t. the heap
- Place the MRC pool right below the MRC_VAR region
- to work with the same DCACHE_RAM_BASE from the native raminit (could
make the CAR linker symbols easily compatible if desired)
This allows CAR setup compatibility between mrc.bin and native
bootpath and also allows for BIOS/memory mappeds region larger than
8MB.
This changes the semantics of CONFIG_DACHE_RAM_MRC_VAR_SIZE to also
include the pool on top of MRC_VAR region.
TESTED on T520 (boots and resumes from S3 with mrc.bin).
