A polling mode I2C master driver. Interfaces for read/write byte

This adds SPI transaction support, and a debug command to read a few
values from the SPI EEPROM.
Note that the SPI controller is normally *disabled* with all its I/Os
high-Z, so this will not interfere with main processor or Servo on the
SPI bus. The bus is only enabled during the SPIROM command itself.

The VMA of the .data segment is in RAM, but we actually put it into FLASH.
The linker doesn't notice if it runs out of flash, so it creates an invalid
image.
This adds an explicit check to be sure it all fits. It also refactors the
region declarations to be more explicit. For vboot-enabled configurations,
CONFIG_SECTION_* - describes the extent of flash for one entire image
CONFIG_FW_* - the region within the SECTION for the firmware only
CONFIG_VBLOCK_* - the region within the RW SECTIONs for the vblocks
CONFIG_VBOOT_ROOTKEY - the region within the RO SECTION for the root key
Look at chip/lm4/config.h for the best example.
