Subject: [PATCH v2] EDAC support for SiFive SoCs

Adds an EDAC platform driver for SiFive SoCs.

This patch was earlier part of the patch series:
'L2 cache controller and EDAC support for SiFive SoCs'
https://lkml.org/lkml/2019/4/15/320
In order to merge L2 cache controller driver without any dependency on EDAC,
this EDAC patch is re-posted separately with updated MAINTAINERS entry.

This patch depends on patch
'RISC-V: sifive_l2_cache: Add L2 cache controller driver for SiFive SoCs'
https://lkml.org/lkml/2019/5/6/255
The EDAC driver registers for notifier events from the L2 cache controller
driver (arch/riscv/mm/sifive_l2_cache.c) for L2 ECC events

The patch is based on Linux 5.1-rc2 and tested on HiFive Unleashed board
with additional board related patches needed for testing can be found at
dev/yashs/L2_cache_controller branch of:
https://github.com/yashshah7/riscv-linux.git

Changes since v1
- Move extern definition into sifive_l2_cache header file
- Replace NOTIFY_STOP with NOTIFY_OK in ecc_err_event()
- Other minor fixes based upon comments against v1
