SFI: add support for v0.81 spec
There are 2 major changes from v0.81 to v0.7: 1. Consolidating the SPIB/I2CB tables into a new DEVS table, which is more expandable and can support other bus types than spi/i2c. 2. Creating a new GPIO table, which list all the GPIO pins used in the platform. However, to avoid breaking current platforms who use SFI v0.7 version firmware, the definitions for SPIB/I2CB will still be kept for a while Signed-off-by: Feng Tang <feng.tang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
