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

Browse Source 
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

* cntl_stuck_hw_workaround - Workaround for I2C engine stuck state
* @dce_i2c_hw: Pointer to dce_i2c_hw structure
*
* If we boot without an HDMI display, the I2C engine does not get initialized
* correctly. One of its symptoms is that SW_USE_I2C does not get cleared after
* acquire, so that after setting SW_DONE_USING_I2C on release, the engine gets
* acquire. After setting SW_DONE_USING_I2C on release, the engine gets
* immediately reacquired by SW, preventing DMUB from using it.
*
* This function checks the I2C arbitration status and applies a release
* workaround if necessary.
