27199e7b64 spi_flash: Add protect support for W25X40 
W25X40 uses a different protection register encoding than our existing
W25Q64 code. Move the SPI ROM option to a config, and add support for
the new part.

BUG=chrome-os-partner:37688
TEST=`make buildall -j`. W25X40 protection code tested in a subsequent
commit.
BRANCH=None

The latest gcc picked up a couple out-of-bounds issues, so
"make buildall" was failing. This fixes them.
