The only reason bus pointer existed in device structure in sconfig was
to allow a node to point to the parent which could be a chip and bus
which is the true parent in device tree hierarchy. Now that chip is no
longer a device, there is no need for separate bus and parent
pointers. This change gets rid of the redundant bus pointer in struct
device in sconfig.

This change adds a new structure "struct chip" to identify elements of
type chip rather than re-using the structure for device. Until now
chip was treated as a device while generating the parse tree and then
device tree postprocessing skipped over all the chip entries in
children and sibling pointers of device nodes.
With this change, the device tree will only contain struct device in
the parsed tree. It helps by avoiding unnecessary pointers to chip
structure as children or next_sibling and then skipping those elements
in post processing. Every device can then hold a pointer to its chip.
When generating static.c, chip structure is emitted before device
structure to ensure that the device structure has chip within its
scope. Externally, the only visible change in static.c should be the
order in which chip/device elements are emitted i.e. previously all
chips under a particular device were emitted to static.c and then the
devices using those chips. Now, all chips are emitted before all the
devices in static.c
