Myles Watson 0fb2a8f081 This patch simplifies the resource allocator by splitting it into distinct 
phases.  One benefit of this is that it makes the call chain easier to follow.

device/device.c:
	Remove references to have_resources.
	Remove read_resources from compute allocate resources.
	Split compute_allocate_resources into two
	1. compute_resource_needs
		A. Traverse the tree depth first
		B. Sum resources
		C. Adjust limits and bases
		D. Update bridge resources sizes
	2. assign_resource_values
		A. Traverse the tree breadth first
		B. Assign resource values

device/device_util.c:
	Remove references to have_resources.

device/pci_device.c:
	Remove saved values stubs (they're not needed now.)
		1. Sizing function restores values
	Fix 64-bit flag masking.
	Add an error message for an invalid value.
	Update pci_record_bridge_resource:
		1. remove compute_allocate_resource call
		2. remove pci_set_resource call
	Update pci_bus_read_resources to read children's too.
	Update pci_set_resource:
		1. change logic for setting zero-size resources
			A. Set range to [limit->limit-2^gran]
				(Could have been any range with base > limit)
		2. remove compute_allocate_resource calls
		3. Change phase4_assign_resources ->phase4_set_resources

device/pci_ops.c:
	Change an error message to be more helpful.

device/root_device.c:
	Remove code for read_resources and set resources.
	Add a .id to the ops.

include/device/device.h:
	Remove have_resources.
	Comment out assign_resources.  I think we could comment out more here.
	Add debugging function prototypes.
	Change phase4_assign_resources to phase4_set_resources.

include/device/resource.h
	Add a IORESOURCE_BRIDGE flag.

device/cardbus_device.c
	Remove compute_allocate_resource call.
	Use probe_resource (doesn't die) instead of find_resource.
