[PATCH 2/3] drm/amd/powerplay/hwmgr: Adjust layout for source code from five if statements

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Thu, 8 Feb 2018 21:01:24 +0100

The script "checkpatch.pl" pointed information out like the following.

WARNING: Comparisons should place the constant on the right side
of the test
WARNING: else is not generally useful after a break or return

Thus fix the affected source code places.
