[PATCH][SRU BIONIC] UBUNTU: [Config]: set CONFIG_EDAC_DEBUG=y for ARM64

Wed Jun 20 20:14:12 UTC 2018

Testing EDAC requires EDAC_DEBUG to be enabled. ARM64 server customers 
currently need to rebuild Ubuntu kernels with this config option to test 
EDAC support. Please consider this SRU to Bionic to enable EDAC_DEBUG 
config option in the kernel.

A patch to enable EDAC_DEBUG was acked and applied to cosmic recently.
