[PATCH v2 1/1] docs: Fix kernel-doc indentation errors

[Luis Felipe Hernandez <luis.hernandez093@gmail.com>]

Fix kernel-doc issues that reported Unexpected indentation errors
durring documentation build (make htmldocs) in CAN, I3C and GPU drivers.

Convert formatting to proper ReST list syntax to resolve warning.

Changes since v1:
- Convert return value descriptions to proper ReST format
- Fix code block introduction with :: syntax  
- Add GPU driver fixes
- Remove SCSI driver (already fixed)
