dt-bindings: use capital "OR" for multiple licenses in SPDX

Documentation/process/license-rules.rst and checkpatch expect the SPDX
identifier syntax for multiple licenses to use capital "OR".  Correct it
to keep consistent format and avoid copy-paste issues.

Correct also the format // -> .* in few Allwinner binding headers as
pointed out by checkpatch:

  WARNING: Improper SPDX comment style for 'include/dt-bindings/reset/sun50i-h6-ccu.h', please use '/*' instead
