MIPS: Remove NETLOGIC support

No (active) developer owns this hardware, so let's remove Linux support.

MIPS: Prevent compiler warning from cop2_{save,restore}

The no-op cases of cop2_save & cop2_restore lead to the following
warnings being emitted during build with recent versions of gcc (tested
using gcc 4.8.3 from the Mentor Sourcery CodeBench 2014.05 toolchain):

In file included from ./arch/mips/include/asm/switch_to.h:18:0,
from kernel/sched/core.c:78:
kernel/sched/core.c: In function 'finish_task_switch':
include/asm-generic/current.h:6:45: warning: value computed is not used [-Wunused-value]
#define get_current() (current_thread_info()->task)

./arch/mips/include/asm/cop2.h:48:32: note: in definition of macro 'cop2_restore'
#define cop2_restore(r) do { (r); } while (0)

Avoid the warning by "using" the value by casting to void.

MIPS: Loongson-3: Enable the COP2 usage

Loongson-3 has some specific instructions (MMI/SIMD) in coprocessor 2.
COP2 isn't independent because it share COP1 (FPU)'s registers. This
patch enable the COP2 usage so user-space programs can use the MMI/SIMD
instructions. When COP2 exception happens, we enable both COP1 (FPU)
and COP2, only in this way the fp context can be saved and restored
correctly.

MIPS: Netlogic: COP2 save/restore code

Add COP2 register state structure and functions for Netlogic XLP. The
RX and TX buffers and status registers are to be saved. Since the
registers are 64-bit, do the implementation in inline assembly which
works on both 32-bit and 64-bit kernels.

asm/processor.h and in asm/cop2.h.
