[PATCH AUTOSEL 5.4 25/57] drm/amdgpu: Correctly initialize thermal controller for GPUs with Powerplay table v0 (e.g Hawaii)

[Sasha Levin]

From: Sandeep Raghuraman <sandy.8...@gmail.com>

[ Upstream commit bbc25dadc7ed19f9d6b2e30980f0eb4c741bb8bf ]

Initialize thermal controller fields in the PowerPlay table for Hawaii
GPUs, so that fan speeds are reported.
