Use SPDX-License-Identifier instead of the license boilerplates. This conversion makes it easier for us to scan the license, then I notice license mismatch problems. The license blocks in denali* indicate GPL-2.0 "only", while the MODULE_LICENSE in denali.c and denali_dt.c is GPL-2.0 "or later" as explained in include/linux/module.h as follows: "GPL" [GNU Public License v2 or later] "GPL v2" [GNU Public License v2] I fixed the MODULE_LICENSE tags, assuming the license blocks are the authors' intention. Also, add missing MODULE_DESCRIPTION/AUTHOR to denali.c While I am touching the license things, I added my credit to denali.c because this driver was largely re-written by me in 2017.
