[ Upstream commit 901245624c7812b6c95d67177bae850e783b5212 ] When a custom powerplay table is provided, we need to update the OD VDDC flag to avoid AVFS being enabled when it shouldn't be.

2020-09-17drm/amdgpu: Fix bug in reporting voltage for CIKSandeep Raghuraman
[ Upstream commit d98299885c9ea140c1108545186593deba36c4ac ] 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.
