From: "Stanley.Yang" <Stanley.Yang@amd.com>

[ Upstream commit a32c6f7f5737cc7e31cd7ad5133f0d96fca12ea6 ]

The ecc_irq is disabled while GPU mode2 reset suspending process,
but not be enabled during GPU mode2 reset resume process.

Changed from V1:
only do sdma/gfx ras_late_init in aldebaran_mode2_restore_ip
delete amdgpu_ras_late_resume function

Changed from V2:
check umc ras supported before put ecc_irq
