[PATCH v2 1/4] platform/x86/uniwill: uniwill-laptop: Rework hwmon feature defines

[Werner Sembach <wse@tuxedocomputers.com>]

From: Armin Wolf <W_Armin@gmx.de>

Split hwmon feature define in smaller parts to accommodate for diverse
hardware. You can now specify the presence of a cpu and/or a gpu temp
sensor separately and if one or 2 fans exists.
