Subject: [PATCH] drm/amdgpu/powerplay: Fix missing break in switch statement

Add missing break statement in order to prevent the code from falling
through to case SMU_Discrete_DpmTable.

This bug was found thanks to the ongoing efforts to enable
-Wimplicit-fallthrough.

Fixes: 34a564eaf528 ("drm/amd/powerplay: implement fw image related smum interface for Polaris.")
