MIPS: Octeon: Remove all unused CIU macros.

Get rid of all unused CIU macros and sort them. Verified with
'make allyesconfig' build test.

[paul.burton@mips.com:
- Also checked via convoluted grep invocation for use of all removed
macros within arch/mips/ & drivers/.]

MIPS: Octeon: Unify QLM data types in CIU header.

Data types 'cvmx_ciu_qlm0' and 'cvmx_ciu_qlm1' are identical in
their usage and structure. Combine them and update the PCIe code.

MIPS: OCTEON: Update register definitions.

Add support for cn68xx, cn61xx, cn63xx, cn66xx and cnf71XX.

Add little-endian register layouts.

Patch cvmx-interrupt-rsl.c for changed definition.

MIPS: Octeon: Update register definitions for CN63XX chips

The CN63XX is a new 6-CPU SOC based on the new OCTEON II CPU cores.

Join some lines back together. This makes some of them exceed 80
columns, but they are uninteresting and this unclutters things.

MIPS: Add Cavium OCTEON processor CSR definitions

Here we define the addresses and bit-fields of the Configuration and
Status Registers (CSRs) for some of the hardware functional units on
the OCTEON SOC.

Definitions are needed for:

CIU -- Central Interrupt Unit.
GPIO -- General Purpose Input Output.
IOB -- Input / Output {Busing,Bridge}.
IPD -- Input Packet Data unit.
L2C -- Level-2 Cache controller.
L2D -- Level-2 Data cache.
L2T -- Level-2 cache Tag.
LED -- Light Emitting Diode controller.
MIO -- Miscellaneous Input / Output.
POW -- Packet Order / Work unit.
