nyan: Fix timestamps and CBFS SPI integration

Nyan is an old board that was committed before several core code
modernizations to timestamp and CBFS code. Not all of those later
patches were correctly integrated with old boards like this, and the
core code has evolved to a point where it doesn't actually boot anymore.

This patch fixes that issue and brings the Nyan boards more in line with
how later ARM platforms look.

BRANCH=None
BUG=None
TEST=My Blaze boots again.
