d7bc23ac8e baytrail: add support for disabling south cluster pci devices
When the southcluster pci devices are listed in the devicetree add
the ability to perform the proper disabling sequence for turning
off devices. This only turns off the pci device interface as well
as put the device into D3Hot. It is not yet known how to put the TXE
device into D3Hot so it's currently not possible to disable that
device.

Also, expose the southcluster_enable_dev() function so that other
devices can call this if they require doing specific things before
disabling the device. The southcluster_enable_dev() is only called
on devices found in the devicetree and if they currently have no
ops associated with them.

BUG=chrome-os-partner:22871
BRANCH=None
TEST=Built and booted through depthcharge. Interrogated
     output to ensure devices were being properly disabled.

452d31ad75 baytrail: introduce pattrs
The pattrs structure is intended for the supporting coreboot
code to reference instead of going back to the source of
the values (msrs, cpuid, etc). It essentially serves as a global
structure for collecting attributes about the platform/processor.

Additionally, the implementation provides a point during boot to
hoook work before device enumeration/initialization by providing
a init() function to soc_intel_baytrail_ops that is called before
device work in the boot state machine.

fda56a6bfd baytrail: add common pci_operations
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.

9a7d7bcea5 baytrail: add initial support
The initial Bay Trail code is intended to support
the mobile and desktop version of Bay Trail. This support
can train memory and execute through ramstage. However,
the resource allocation is not curently handled correctly.
The MRC cache parameters are successfully saved and reused
after the initial cold boot.
