[PATCH v2 0/3] Cleanups in amd64_edac and removal of legacy EDAC sysfs interface

[Avadhut Naik <avadhut.naik@amd.com>]

This patchset undertakes some cleanups in the amd64_edac module and
removes the legacy EDAC sysfs interface since it has been obsolete for
more than a decade.

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 removes the old 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.

Changes in v2:
 - Drop the patch that set zn_regs_v2 flag for all SOCs based on Family
1Ah and later.
 - Change MAX_CTL_NAMELEN macro from 20 to 19.
 - Modify commit message of the second patch per feedback received.
 - Skip deprecation and just remove the old EDAC sysfs interface.
