[PATCH 03/30] IRQ-affinity.txt: standardize document format

[Mauro Carvalho Chehab]

Each text file under Documentation follows a different
format. Some doesn't even have titles!

Change its representation to follow the adopted standard,
using ReST markups for it to be parseable by Sphinx:

- Add a title for the document;
- mark literal blocks as such;
- use a bulleted list for changelog.

 Default mask is 0xffffffff.
 
 Here is an example of restricting IRQ44 (eth1) to CPU0-3 then restricting

 As can be seen from the line above IRQ44 was delivered only to the first four
 processors (0-3).
 Now lets restrict that IRQ to CPU(4-7).

 This time around IRQ44 was delivered only to the last four processors.
 i.e counters for the CPU0-3 did not change.
 
-Here is an example of limiting that same irq (44) to cpus 1024 to 1031:

 Note that to do this with a bitmask would require 32 bitmasks of zero
 to follow the pertinent one.
