[PATCH][drm-next] drm/amdgpu/powerplay: fix missing break in switch statements

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

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")

Fixes: 18aafc59b106 ("drm/amd/powerplay: implement fw related smu interface for iceland.")
