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

This commit adds support for describing USB ports in devicetree.cb.
It allows a USB port location to be described in the tree with
configuration information, and ACPI code to be generated that
provides this information to the OS.
A new scan_usb_bus() is added that will scan bridges for devices so
a tree of ports and hubs can be created.
The device address is computed with a 'port type' and a 'port id'
which is flexible for SOC to handle depending on their specific USB
setup and allows USB2 and USB3 ports to be described separately.
For example a board may have devices on two ports, one with a USB2
device and one with a USB3 device, both of which are connected to an
xHCI controller with a root hub:
xHCI
|
RootHub
| |
USB2[0] USB3[2]
device pci 14.0 on
chip drivers/usb/acpi
register "name" = ""Root Hub""
device usb 0.0 on

end

The devicetree data structures have been available in more than just
ramstage and romstage. In order to provide clearer and consistent
semantics two new macros are provided:
1. DEVTREE_EARLY which is true when !ENV_RAMSTAGE
2. DEVTREE_CONST as a replacment for ROMSTAGE_CONST
The ROMSTAGE_CONST attribute is used in the source code to mark
the devicetree data structures as const in early stages even though
it's not just romstage. Therefore, rename the attribute to
DEVTREE_CONST as that's the actual usage. The only place where the
usage was not devicetree related is console_loglevel, but the same
name was used for consistency. Any stage that is not ramstage has
the const C attribute applied when DEVTREE_CONST is used.

We thought about two ways to do this change. The way we decided to try
was to
1. drop all ops from devices in romstage
2. constify all devices in romstage (make them read-only) so we can
compile static.c into romstage
3. the device tree "devices" can be used to read configuration from
the device tree (and nothing else, really)
4. the device tree devices are accessed through struct device * in
romstage only. device_t stays the typedef to int in romstage
5. Use the same static.c file in ramstage and romstage
We declare structs as follows:
ROMSTAGE_CONST struct bus dev_root_links[];
ROMSTAGE_CONST is const in romstage and empty in ramstage; This
forces all of the device tree into the text area.
So a struct looks like this:
static ROMSTAGE_CONST struct device _dev21 = {
#ifndef __PRE_RAM__
.ops = 0,
#endif
.bus = &_dev7_links[0],
.path = {.type=DEVICE_PATH_PCI,{.pci={ .devfn = PCI_DEVFN(0x1c,3)}}},
.enabled = 0,
.on_mainboard = 1,
.subsystem_vendor = 0x1ae0,
.subsystem_device = 0xc000,
.link_list = NULL,
.sibling = &_dev22,
#ifndef __PRE_RAM__
.chip_ops = &southbridge_intel_bd82x6x_ops,
#endif
.chip_info = &southbridge_intel_bd82x6x_info_10,
.next=&_dev22
};

mainboard_config never worked right, at least not since we've had sconfig.
Hence, drop mainboard/<vendor>/<device>/chip.h and fix up the mainboards that
tried to use it anyways.

This patch adds support for autogenerating the MPTABLE from
devicetree.cb. This is done by a write_smp_table() declared
weak in mpspec.c. If the mainboard doesn't provide it's own
function, this generic implementation is called.
Syntax in devicetree.cb:
ioapic_irq <APICID> <INTA|INTB|INTC|INTD> <INTPIN>
The ioapic_irq directive can be used in pci and pci_domain
devices. If there's no directive, the autogen code traverses
the tree back to the pci_domain and stops at the first device
which such a directive, and use that information to generate the
entry according to PCI IRQ routing rules.

Mainboard and chip Kconfig files have several build options that
are redundant with information in devicetree.cb. This patch enables
sconfig to auto-generate equivalent configuration.
sconfig -s
Generates mainboard's static.c file, as before.
sconfig -b
This operation creates mainboard's bootblock init code. By default,
for every chip listed in mainboard/devicetree.cb, if there is a
chip/bootblock.c file, the init function is called.
A mainboard/bootblock.c file can be added to override default
behaviour.
sconfig -k
This operation generates select -options for component paths.

Without this patch typos in component names in devicetree.cb cause
the component to be silently ignored.
