[PATCH 5.16 254/285] drm/amdgpu/smu10: fix SoC/fclk units in auto mode

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

commit 2f25d8ce09b7ba5d769c132ba3d4eb84a941d2cb upstream.

SMU takes clock limits in Mhz units. socclk and fclk were
using 10 khz units in some cases. Switch to Mhz units.
Fixes higher than required SoC clocks.

Fixes: 97cf32996c46d9 ("drm/amd/pm: Removed fixed clock in auto mode DPM")
