Subject: [PATCH v4 0/6] Use composable cache instead of L2 cache

Since composable cache may be L3 cache if private L2 cache exists, we
should use its original name "composable cache" to prevent confusion.

This patchset contains the modification which is related to ccache, such
as DT binding and EDAC driver.

The DT binding is based on top of Conor's patch, it has got ready for
merging, and it looks that it would be taken into the next few 6.0-rc
version. If there is any change, the next version of this series will be
posted as well.

Change log in v4:
 - Change the return value from from ENODEV to ENOENT
 - Apply pr_fmt refinement to all pr_err

Change log in v3:
 - Merged the EDAC patch into L2 rename patch
 - Define the macro for register shift and refine the relative code
 - Fix some indent issues

Change log in v2:
 - Separate the rename and diff to different patches
