[PATCH 10/18] drm/amdgpu: add ip block with instance

[boyuan.zhang]

From: Boyuan Zhang <boyuan.zh...@amd.com>

Add instance number to ip block to track which instance the ip block
belongs to.

Also, add a new function to allow ip block to save the instance number
along with other ip block driver information.

Signed-off-by: Boyuan Zhang <boyuan.zh...@amd.com>
