usb: dwc3: dwc3-octeon: Convert to glue driver

DWC3 as implemented in Cavium SoC is using UCTL bridge unit
between I/O interconnect and USB controller.

Currently there is no bond with dwc3 core code, so if anything goes
wrong in UCTL setup dwc3 is left in reset, which leads to bus error
while trying to read any device register. Thus any failure in UCTL
initialization ends with kernel panic.

To avoid this move Octeon DWC3 glue code from arch/mips and make it
proper glue driver which is used instead of dwc3-of-simple.

kbuild: centralize .dts->.dtb rule

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.

MIPS: Octeon: Add device tree source files.

The two device tree files octeon_3xxx.dts and octeon_68xx.dts are
trimmed by code in a subsequent patch to reflect the hardware actually
present on the board. To this end several properties that are not
part of the declared bindings are added to aid in trimming off
unwanted nodes. Since the device tree and the code that trims it are
bound into the kernel binary, these 'marker' properties never escape
into the wild, and are purely an implementation detail of the kernel
early boot process. This is done for backwards compatibility with
existing boards (identified by a board type enumeration value by their
bootloaders). New boards will always pass a device tree from the
bootloader, the built-in trees are ignored in this case.
