drm/amd/display: Fix misuse of /** to /* in 'dce_i2c_hw.c'

Fix the comment style before cntl_stuck_hw_workaround() by replacing
'/**' with '/*' since it is not a kdoc comment.

Fixes the below with gcc W=1:
display/dc/dce/dce_i2c_hw.c:380: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
* If we boot without an HDMI display, the I2C engine does not get
  initialized
