soc/intel/quark: Fix I2C driver

Fix the following issues:
*  A raw read is described by a single read segment, don't assert.
*  Support reads longer than the FIFO size.
*  Support writes longer than the FIFO size.
*  Use the 400 KHz clock by default.
*  Remove the error displays since vboot device polling generates
   errors.

TEST=Build and run on Galileo Gen2
