pistachio: change memory layout as to allow bigger CBFS cache

As the payload increases in size, a bigger CBFS cache is required.
Therfore, bootblock, romstage and the cbfs cache were placed in
GRAM (128 K) and the stack and cbmem console were moved to
SRAM (64 K). With the exception of CBFS cache, the sizes of all
the other regions remains the same.

BUG=chrome-os-partner:31438
TEST=tested on Pistachio FPGA and bring up board;
     behavior was as expected.
BRANCH=none
