drm/amd/display: dmub_replay: don't use kernel-doc markers

These functions don't use kernel-doc notation for comments so
don't begin each comment block with the "/**" kernel-doc marker.

This prevents a bunch of kernel-doc warnings:

dmub_replay.c:37: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
dmub_replay.c:37: warning: missing initial short description on line:
 * Get Replay state from firmware.
dmub_replay.c:66: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
dmub_replay.c:66: warning: missing initial short description on line:
 * Enable/Disable Replay.
dmub_replay.c:116: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
dmub_replay.c:116: warning: missing initial short description on line:
 * Set REPLAY power optimization flags.
dmub_replay.c:134: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
dmub_replay.c:134: warning: missing initial short description on line:
 * Setup Replay by programming phy registers and sending replay hw context values to firmware.
and 10 more similar warnings.
