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
