Move PCI bus below simplebus for Broadcom XLP

This will enable us to do common allocation code for memory and
interrupts for SoC devices as well as PCI devices.

Remove run-time allocation of XLP IRQs

Follow the same static IRQ to Interrupt Table Entry mapping as the other
OS supported on XLP.

Add netlogic,xlp-pic as interrupt controller for XLP

Add an empty driver for netlogic,xlp-pic to ensure that the device tree
is correct and has an interrupt controller.

Integrate device-tree upstream files into the build process:
(1) Invoke cpp to bring in files via #include (although the old
/include/ stuff is supported still).
(2) bring in files from either vendor tree or freebsd-custom files
when building.
(3) move all dts* files from sys/boot/fdt/dts to
sys/boot/fdt/dts/${MACHINE} as appropriate.
(4) encode all the magic to do the build in sys/tools/fdt/make_dtb.sh
so that the different places in the tree use the exact same logic.
(5) switch back to gpl dtc by default. the bsdl one in the tree has
significant issues not easily addressed by those unfamiliar with
the code.

Add correct range parameter in XLP DTS

r239274 added support for ranges. Update XLP DTS to provide the correct
range parameter for the XLP SoC bus. Also fix bus_space_map method
for XLP bus space.

Support for booting XLP using FDT.

- update xlp_machdep.c to read arguments from FDT if FDT support is
compiled in.
- define rmi_uart_bus_space, and use it as fdtbus_bs_tag
- update conf files for FDT support
- add default dts file xlp-basic.dts
