nyan: Enable the cbmem console on nyan and allocate space for it in SRAM.
This change takes about 8K of space away from the cbfs cache and repurposes it for the cbmem console buffer. This is a little more than twice the space we currently need for the bootblock and ROM stage to give us some room to grow and for extra debug output if needed. BUG=None TEST=Built and booted on nyan. Checked the cbmem output.
