Subject: drm/amd/pm: Fix output of pp_od_clk_voltage

From: Jonatas Esteves <jntesteves@xxxxxxxxx>

commit 40baba5693b9af586dc1063af603d05a79e57a6b upstream.

Printing the other clock types should not be conditioned on being able
to print OD_SCLK. Some GPUs currently have limited capability of only
printing a subset of these.

Since this condition was introduced in v5.18-rc1, reading from
`pp_od_clk_voltage` has been returning empty on the Asus ROG Strix G15
(2021).
