2014-01-31baytrail: set host memory mapAaron Durbin
Prior to this commit the coreboot resource allocator was not using proper addresses. That's not surprising there wasn't any code to initialize the resources properly. This commit initializes the memory map accoring to the BUNIT registers. BUG=chrome-os-partner:22860 BUG=chrome-os-partner:22862 BRANCH=None TEST=Built and booted. Noted output for resource assignments is sane.

2014-01-31baytrail: add common pci_operationsAaron Durbin
The coreboot device modeling for pci devices wants a pci_operations structure for all devices. This structure just sets the subsystem vendor and device id. Add a common one that all the other pci drivers can use for Bay Trail. BUG=chrome-os-partner:22860 BRANCH=None TEST=Built and booted while utilizing this new structure.

2014-01-31baytrail: initialize graphics before MRCAaron Durbin
The graphics device needs to have its resource contraints initialized before running the reference code. Right now just use a 256MiB aperture, 32MiB of stolen memory data, and 2MiB GTT memory. BUG=chrome-os-partner:22869 BRANCH=None TEST=Built and booted. Noted amount of stolen memory matches configuration as well as BAR size within the graphics device.
