drm/amd/pm/powerplay/hwmgr/ppatomctrl: Remove redundant ternary operators

For ternary operators in the form of "a ? true : false", if 'a' itself
returns a boolean result, the ternary operator can be omitted. Remove
redundant ternary operators to clean up the code. Swap variable positions
on either side of '!=' to enhance readability.
