drm/amdgpu/powerplay: fix missing break in switch statements



[ Upstream commit 14b284832e7dea6f54f0adfd7bed105548b94e57 ]

There are several switch statements that are missing break statements.
Add missing breaks to handle any fall-throughs corner cases.

Detected by CoverityScan, CID#1457175 ("Missing break in switch")
