Always have the error injection i/f available, even if there is no
debugfs or EDAC_DEBUG enabled. We need this for testing production
kernels and environments.

Thus, the entry moves from:

 /sys/kernel/debug/edac/mc0/inject_ctrl

to:

 /sys/devices/system/edac/mc/mc0/inject_ctrl

No other changes of the interface.

Assinging correct names of the 'hb_mc_edac' and 'hb_l2_edac' edac
modules for module, controller and device. Reported values for
Highbank in dmesg are now:

 EDAC MC0: Giving out device to module hb_mc_edac controller
 calxeda,hb-ddr-ctrl: DEV fff00000.memory-controller (INTERRUPT)

 EDAC DEVICE0: Giving out device to module hb_l2_edac controller

Implement edac support for Calxeda ECX-2000.

The ECX-2000 memory controller is similar to Highbank but has
different register bases for error and interrupt registers. There is
an own device tree name "calxeda,ecx-2000-ddr-ctrl" for identification
and initialization of the ECX-2000 and its base addresses.

Register and enable interrupts after the edac registration. Otherwise
incomming ecc error interrupts lead to crashes during device setup.

Fixing this in drivers for mc and l2.

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, and __devexit
from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

This removes an open coded simple_open() function and replaces file
operations references to the function with simple_open() instead.

platforms support a single 4GB mini-DIMM with 1-bit correction and 2-bit
detection.
