Split the AER stats into multiple sysfs atributes. Note that
this changes the ABI of the AER stats, but hopefully, there
aren't active users that need to change. This is how the AERs
are being exposed now:

Each file is has a single counter value. Single file containing all
stats was frowned upon and discussed here:

I personally think that this makes it a little overwhelming for a human,
e.g. I could look at total but don't exactly know while file to look at
next in order to drill down. But I couldn't think of any other way. Some
problems I'd have liked to fix but they require deeper surgery:

* Now each PCI device sysfs node will have a sub-directory called aer_stats.
  (The subdirectory will have attributes only if it supports AER, but
   the sub directory will always be present). 

* This patch isn't re-using the strings array like it was using earlier.
  I thought of adding the attribute group at run time, so it will take
  care of both the problems, but can only do that after device_add() call,
  I think.

If we are comfortable introducing a call to a new function
pci_aer_stats_init() after call to device_add() in in pci_device_add(),
the above problems can be fixed.

You need a Documentation/ABI/ update for the new sysfs files before we
can properly review this to see if you are doing what you think you are
doing :)
