request_irq() is preferred over setup_irq(). Invocations of setup_irq()
occur after memory allocators are ready.
Per tglx[1], setup_irq() existed in olden days when allocators were not
ready by the time early interrupts were initialized.
Hence replace setup_irq() by request_irq().
remove_irq() has been replaced by free_irq() as well.
There were build error's during previous version, couple of which was
reported by kbuild test robot <lkp@intel.com> of which one was reported
by Thomas Bogendoerfer <tsbogend@alpha.franken.de> as well. There were a
few more issues including build errors, those also have been fixed.

Rename macro nlm_cop2_enable() to nlm_cop2_enable_irqsave() and the macro
nlm_cop2_restore to nlm_cop2_disable_irqrestore(). The new names will
reflect the functionality better, and will make nlm_cop2_restore()
available to be used later in COP2 save/restore patch.

The sel argument os nlm_read_c2_status() was not used and the macro
returned the sel 0 in all cases. Fix this by defining two macros:
nlm_read_c2_status0() and nlm_read_c2_status1() to return the two
status registers.
Add functions to write to the status registers as well.

On XLR/XLS, the cpu cores communicate with fast on-chip devices
(e.g. network accelerator, security engine etc.) using the Fast
Messaging Network(FMN). The FMN queues and credits needs to be
configured and intialized before it can be used.
The co-processor 2 on XLR/XLS CPU cores has registers for FMN access,
and the XLR/XLS has custom instructions for sending and loading
messages. The FMN can deliver also per-cpu interrupts when messages
are available at the CPU.
This patch adds FMN initialization, adds interrupt setup and handling,
and also provides support for sending and receiving FMN messages.
