[PATCH AUTOSEL 4.19 26/59] drm/amdgpu/powerplay: fix typo in mvdd table setup

[Sasha Levin]

From: Alex Deucher <alexander.deucher at amd.com>

[ Upstream commit 598c30dbcc9434706f29a085a8eba4730573bcc2 ]

Polaris and vegam use count for the value rather than
level.  This looks like a copy paste typo from when
the code was adapted from previous asics.

I'm not sure that the SMU actually uses this value, so
I don't know that it actually is a bug per se.
