ghes: add the needed hooks for EDAC error report
In order to allow reporting errors via EDAC, add hooks for:
1) register an EDAC driver;
2) unregister an EDAC driver;
3) report errors via EDAC.
As the EDAC driver will need to access the ghes structure, adds it
as one of the parameters for ghes_do_proc.
