drivers-edac: add Cell MC driver

Adds driver for the Cell memory controller when used without a Hypervisor such
as on the IBM Cell blades.  There might still be some improvements to do to
this such as finding if it's possible to properly obtain more details about
the address of the error but it's good enough already to report CE counts
which is our main priority at the moment.
