[PATCH 89/95] drm/amdgpu: Move ualink ip version related changes

[Alex Deucher <alexander.deucher@amd.com>]

From: Lijo Lazar <lijo.lazar@amd.com>

Move more IP version specific related things to ualink version file.
Use soc v1.0 IH client id defintion and define mpnht interrupt source
id in ivsrcid header.
