[PATCH 381/459] drm/amd/display: Fix DCFCLK and SOCCLK not set

[Alex Deucher]

From: Ilya Bakoulin <Ilya.Bakoulin at amd.com>

[Why]
If voltage level > 0, DCFCLK and SOCCLK could be 0 during DML
calculations, which ended up causing an assert.

[How]
Initialize dcfclk_mhz and socclk_mhz values according to the
voltage level.
