MN10300: cleanup IRQ affinity setting
The irq_set_affinity handler for the mn10300 cpu pic had some hard-coded IRQs
which were not to be migrated from one cpu to another. This patch cleans those
up by using a combination of IRQF_NOBALANCING and specialized irq chips with
no irq_set_affinity handler. This maintains the previous behavior by using
generic IRQ interfaces rather than hard coding IRQ numbers in the default
irq_set_affinity handler.

doc: fix broken references
There are numerous broken references to Documentation files (in other
Documentation files, in comments, etc.). These broken references are
caused by typo's in the references, and by renames or removals of the
Documentation files. Some broken references are simply odd.
Fix these broken references, sometimes by dropping the irrelevant text
they were part of.

So could move kstat_irqs array to irq_desc struct.
(s390, m68k, sparc) are not touched yet, because they don't support genirq

MN10300: Fix IRQ handling
Fix the IRQ handling on the MN10300 arch.
This patch makes a number of significant changes:
(1) It separates the irq_chip definition for edge-triggered interrupts from
the one for level-triggered interrupts.
This is necessary because the MN10300 PIC latches the IRQ channel's
interrupt request bit (GxICR_REQUEST), even after the device has ceased to
assert its interrupt line and the interrupt channel has been disabled in
the PIC. So for level-triggered interrupts we need to clear this bit when
we re-enable - which is achieved by setting GxICR_DETECT but not
GxICR_REQUEST when writing to the register.
Not doing this results in spurious interrupts occurring because calling
mask_ack() at the start of handle_level_irq() is insufficient - it fails
to clear the REQUEST latch because the device that caused the interrupt is
still asserting its interrupt line at this point.
(2) IRQ disablement [irq_chip::disable_irq()] shouldn't clear the interrupt
request flag for edge-triggered interrupts lest it lose an interrupt.
(3) IRQ unmasking [irq_chip::unmask_irq()] also shouldn't clear the interrupt
request flag for edge-triggered interrupts lest it lose an interrupt.
(4) The end() operation is now left to the default (no-operation) as
__do_IRQ() is compiled out. This may affect misrouted_irq(), but
according to Thomas Gleixner it's the correct thing to do.
(5) handle_level_irq() is used for edge-triggered interrupts rather than
handle_edge_irq() as the MN10300 PIC latches interrupt events even on
masked IRQ channels, thus rendering IRQ_PENDING unnecessary. It is
sufficient to call mask_ack() at the start and unmask() at the end.
(6) For level-triggered interrupts, ack() is now NULL as it's not used, and
there is no effective ACK function on the PIC. mask_ack() is now the
same as mask() as the latch continues to latch, even when the channel is
masked.
Further, the patch discards the disable() op implementation as its now the same
as the mask() op implementation, which is used instead.
It also discards the enable() op implementations as they're now the same as
the unmask() op implementations, which are used instead.
