mainboard/intel/galileo: Add vboot support

Add the necessary files and changes to support vboot.

TEST=Build and run on Galileo Gen2 with a SparkFun CryptoShield

1.  Obtain and install a SparkFun CryptoShield.
    https://www.sparkfun.com/products/13183

2.  Edit src/mainboard/intel/galileo/Kconfig to select
    VBOOT_WITH_CRYPTO_SHIELD

3.  Use make menuconfig to update the config values and select a
    payload that will fit.  I used SeaBIOS which does not boot.

4.  Build coreboot

5.  Use the command file below to generate the signed coreboot image.

6.  Flash build/coreboot.rom onto the Galileo board

7.  The test is successful if verstage detects that it needs recovery
    after Phase 1.  This is expected because the image does not contain
    the GBB section.

8.  Flash build/coreboot.signed.bin onto the Galileo board

9.  The test is successful if verstage reaches Phase 4 and selects SLOT
    A to load the rest of the files.
