[PATCH 6.7 092/162] drm/amdgpu/pm: Fix the power1_min_cap value

From: Ma Jun <Jun.Ma2@amd.com>

commit 7968e9748fbbd7ae49770d9f8a8231d8bce2aebb upstream.

It's unreasonable to use 0 as the power1_min_cap when
OD is disabled. So, use the same lower limit as the value
used when OD is enabled.

Fixes: 1958946858a6 ("drm/amd/pm: Support for getting power1_cap_min value")
