Subject: drm/amdkfd: add renoir kfd device info (v2)
Git-commit: 2b9c2211197634221b9ba05cddc938c8fdfee2c8
Patch-mainline: v5.5-rc1
References: bsc#1152489
This patch inits renoir kfd device info, so we treat renoir as "dgpu"
(bypass iommu v2). Will enable needs_iommu_device till renoir iommu is ready.
v2: rebase and align the drm-next
