meta-crownbay: new layer for E6xx/EG20T systems

This layer provides support for Tunnel Creek + Topcliff Intel systems
to laverne (0.90).

It supports the E6xx embedded on-chip graphics via the Intel Embedded
Media and Graphics Driver (EMGD) 1.5 Gold Driver.

The EMGD and EG20T PCH kernel drivers are of course GPL'ed and are
submitted in a separate patchset for the 2.6.34 yocto kernel.

The userspace X drivers and supporting libraries however are closed
and need to be manually copied into the layer before building.  The
details on how to do this can be found in the README doc in
meta-crownbay/.
