Adds new hardware and interface definitions.
Adds new interface routines - utilizing the reorganized layout of the
driver. Adds SLI-4 specific functions for attachment, initialization,
teardown, etc.

+ * EG. To get the value of the bit field from the above example:
+ * struct temp t1;
+ * value = bf_get(example_bit_field, &t1);
+ * And then to set that bit field:
+ * bf_set(example_bit_field, &t1, 2);
