drm/vmwgfx: fix kernel-doc warnings in vmwgfx_drv.h

Fix 45+ kernel-doc warnings in vmwgfx_drv.h:
- spell a struct name correctly
- don't have structs between kernel-doc and its struct
- end description of struct members with ':'
- start all kernel-doc lines with " *"
- mark private struct member and enum value with "private:"
- add kernel-doc for enum vmw_dma_map_mode
- add missing struct member comments
- add missing function parameter comments
- convert "/**" to "/*" for non-kernel-doc comments
- add missing "Returns:" comments for several functions
- correct a function parameter name

to eliminate kernel-doc warnings (examples):
