baytrail: enable caching and prefetching in spi controller
The default mode of the SPI controller has prefetching disabled.
That obviously has a performance impact. Enable both caching
and prefetching to make booting faster. This has a significant
impact on streaming data out of SPI.
BUG=chrome-os-partner:24085
BRANCH=None
TEST=Built and booted rambi. Payload loading step went from ~285ms
to ~54ms.
