Subject: [PATCH 0/4] Cleanups in amd64_edac

This patchset undertakes some cleanups in the amd64_edac module.

The first patch removes explicit assignment of the ctl_name string and
instead generates it at runtime using scnprintf.

The second patch removes the NUM_CONTROLLERS macro and instead uses the
max_mcs variable to determine the size of chipselect array.

The third patch sets zn_regs_v2 flag for all SOCs in Family 1Ah and later.

The fourth patch initiates deprecation of the legacy EDAC sysfs interface.

NOTE:
These cleanups were earlier submitted as part of the set adding EDAC
support for AMD's newer Family 1Ah-based SOCs.[1] However, since the
support patches were critical to enabling EDAC on newer AMD SOCs and
since these cleanups were still under review, the set was split up.
