Sandeep Raghuraman 349eb8ed73 drm/amdgpu: Fix bug in reporting voltage for CIK
[ Upstream commit d98299885c ]

On my R9 390, the voltage was reported as a constant 1000 mV.
This was due to a bug in smu7_hwmgr.c, in the smu7_read_sensor()
function, where some magic constants were used in a condition,
to determine whether the voltage should be read from PLANE2_VID
or PLANE1_VID. The VDDC mask was incorrectly used, instead of
the VDDGFX mask.

This patch changes the code to use the correct defined constants
(and apply the correct bitshift), thus resulting in correct voltage reporting.
