[PATCH v2] drm/amd: Add missing definitions for `SMU_MAX_LEVELS_VDDGFX`

[Mario Limonciello]

It is reported that on a Topaz dGPU the kernel emits:
	amdgpu: can't get the mac of 5

This is because there is no definition for max levels of VDDGFX
declared for SMU71 or SMU7. The correct definition is VDDC so
use this.
