[PATCH] docs: fix doc warning for DC_HDCP_LC_ENABLE_SW_FALLBACK in amd_shared.h

[Rahul Kumar]

Fixes a kernel-doc warning by correctly documenting the enum value
`DC_HDCP_LC_ENABLE_SW_FALLBACK` in the DC_DEBUG_MASK enum.

The previous documentation was incorrectly formatted and incomplete.
Updated to follow proper kernel-doc syntax with a full description.

Verified fix using `make htmldocs`, and the warning is no longer present.
