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
BUG=b:80081934
TEST=Verified that abuild is successful for all boards. Also, verified
that static.c generated for eve, kahlee, scarlet, asrock imb_a180 is
unchanged from before in node definitions.

GCC 7.1 found an int-in-bool-context in northbridgeinit.c. The logical

`&`.
Also fix off-by-one error with the bitmasks.

After FSP-S, a device on PCI function n will be function swapped
to function 0 if there is no device presnet on function 0.
It needs some modification for DT and causes mismatches between
software configuration and hardware schematic. This patch is
from d779605, which swaps the devfn of the first enabled device
in DT and function 0 resides in a PCI device.
BUG=b:80105785
BRANCH=None
TEST=Make sure the device is still enabled after coalescence with
device on bus 0 and w/o device on bus 0. Test with suspend
and resume and ensure it's consistent.
