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.
