igafb driver hasn't compiled since at least kernel v2.6.34 as
commit 6016a363f6b5 ("of: unify phandle name in struct device_node")
missed updating igafb.c to use dp->phandle instead of dp->node.

- TODO:
- Despite of IGA Card has advanced graphic acceleration,
- initial version is almost dummy and does not support it.
- Support for video modes and acceleration must be added
- together with accelerated X-Windows driver implementation.
-
- Most important thing at this moment is that we have working
