Subject: [PATCH 5.19 0386/1157] drm/amd: Dont show warning on reading vbios values for SMU13 3.1

From: Mario Limonciello <mario.limonciello@....com>

[ Upstream commit 1320d6c7b0deb7219701a55397e93e6c73d00366 ]

Some APUs with SMU13 are showing the following message:
`amdgpu 0000:63:00.0: amdgpu: Unexpected and unhandled version: 3.1`

This warning isn't relevant for smu info 3.1, as no bootup information
is present in the table.

Fixes: 593a54f18031 ("drm/amd/pm: correct the way for retrieving bootup clocks")
