Add a default device tree fie for XLP9XX boards, and add code to use
this device tree if no DTB is passed to the kernel.

Add a default built-in device tree for XLP2xx SoC. The new file
xlp_fvp.dts has updated entries for I2C and memory.

This enables us to have a default device tree per SoC family to be built
into the kernel. The default device tree for XLP3xx has been added as part
of this change. Later this can be used to provide support default boards
for XLP2xx and XLP9xx SoCs.
Kconfig options are provided for each default device tree so that just the
needed ones can be selected to be built into the kernel.

All architectures that use cmd_dtc do so in almost the same way. Create
a central build rule to avoid duplication. The one difference is that
most current uses of dtc build $(obj)/%.dtb from $(src)/dts/%.dts rather
than building the .dtb in the same directory as the .dts file. This
difference will be eliminated arch-by-arch in future patches.
MIPS is the exception here; it already uses the exact same rule as the
new common rule, so the duplicate is removed in this patch to avoid any
conflict. arch/mips changes courtesy of Ralf Baechle.
Update Documentation/kbuild to remove the explicit call to cmd_dtc from
the example, now that the rule exists in a centralized location.

Provide a config option to embed a device tree for XLP evaluation
boards. This DTB will be used if the firmware does not pass in a
device tree pointer.
