sbxxx: Set SPI clock to 16.5 MHz and disable fast reads

Do not rely on broken firmware to set up the SPI configuration correctly.
Some boards fail with flashrom because the firmware chose too high speeds
for the alternate SPI mode which flashrom uses. Temporarily change the
clock to the lowest common value of 16.5 MHz.

Also, disable fast reads just to be safe.

Corresponding to flashrom svn r1750.
