pistachio: modify memory layout
With the code now running on the FPGA board it makes sense to correct
the memory layout definitions to match the actual hardware.
Note that the latest FPGA board firmware introduced support of the
additional 128KB of SRAM (called GRAM) at base address of 0x9a000000.
These are still interim values, which will be tweaked when the actual
bring up board is available.
BRANCH=none
BUG=chrome-os-partner:31438
TEST=the code put into SPI NOR flash boots all the way to ramstage.
