[PATCH 5.15 150/177] drm/amd/pm: fix reading SMU FW version from amdgpu_firmware_info on YC

[Greg Kroah-Hartman]

From: Mario Limonciello <mario.limonciello@xxxxxxx>

commit dcd10d879a9d1d4e929d374c2f24aba8fac3252b upstream.

This value does not get cached into adev->pm.fw_version during
startup for smu13 like it does for other SMU like smu12.
