Subject: drm/amdkfd: remove kgd_dev declaration and initialization
Git-commit: b5d1d755c1344075d4f16a3e6183ed04b4d022ef
Patch-mainline: v5.17-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225

Completes removal of kgd_dev. Direct references to amdgpu_device objects
should now be used instead.
