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.

Move the common code for saving and restoring platform specific COP2
registers to switch_to(). This will make supporting new platforms (like
Netlogic XLP) easier.
The platform specific COP2 definitions are to be specified in
asm/processor.h and in asm/cop2.h.

The notifiers may be called at any time, so the notifier_block cannot
be in init memory.

Away with the daemons of ifdef; get ready for future COP2 users.
