[PATCH v2 2/4] drm/amdkfd: add kfd_device_info_init function

[Graham Sider]

Initializes device_info structs given either asic_type (enum) if GFX
version is less than GFX9, or GC IP version if greater. Also takes in vf
and the target compiler gfx version.

Inclusion/exclusion to certain conditions for certain GC IP versions may
be necessary on npi bringup on a case-by-case basis, but for the most
part should be minimal (e.g. adding one || asic_version == IP_VERSION(X ,X, X) case).
