This patch series adds an L2 cache controller driver with DT documentation
for SiFive FU540-C000.

These two patches were initially 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,
the L2 cache controller patches are re-posted separately in this series.

The patchset 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

Change history:
v2
- Mention the valid values for cache properties in DT documentation
- Remove the unnecessary property 'reg-names'
- Add "cache" to supported compatible string property
- Remove conditional checks from debugfs functions in sifive_l2_cache.c
