[PATCH 07/12] drm/amd/display: correct some hdcp variable naming

From: Wenjing Liu <wenjing.liu at amd.com>

[why]
In HDCP update stream config interface, some variables are named as
xxx_supported, but in fact the variable indicates whether or not xxx_enabled.
Correct the naming so it is less confusing to read the code.
