[PATCH v2] Port Display drivers from FreeBSD

[Vijay Kumar Banerjee]

Hello all,

In this version 2 of the patch, I have fixed the issues pointed
out in review of the first version. I've only sent the port
patches here as the import ones are just copy of FreeBSD sources.

With this patchset the tda0 device is created and attached to the
iicbus, the am335x_lcd driver attaches and creates the fb0 device
and with the 5/6 and 6/6 patch, the fbd is attached to fb0 and the
fb0 device entry is created.

This has been tested on the hardware and the fb0 device is present
and there are no warning during initialization. As noted by 
Christian, this will be merged after there's some I/O is done and
something can be printed on the screen using the framebuffer. For
that I've started with the mmap work and eventually if it works out
the patch 6/6 needs to be modified a bit to include the fb_mmap into
the port commit. Hence, after the mmap work, the v3 of this Patch
will be mergeable. 

Thanks,
Vijay
