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

dt-bindings: clock: Add D1 CAN bus gates and resets

The D1 CCU contains gates and resets for two CAN buses. While the CAN
bus controllers are only documented for the T113 SoC, the CCU is the
same across all SoC variants.

The D1 has a CCU and a R_CCU (PRCM CCU) like most other sunxi SoCs, with
3 and 4 clock inputs, respectively. Add the compatibles and bindings.
