EDAC, sb_edac: Get rid of ->show_interleave_mode() 

Function sbridge_register_mci() sets pvt->info.show_interleave_mode
to knl_show_interleave_mode() on Knight's Landing and
show_interleave_mode() anywhere else.

Merge show_interleave_mode() and knl_show_interleave_mode() in a single
implementation and use it without an indirect function pointer.
