drm/amdgpu: Add sysfs nodes to get xcp details
Add partition config nodes in sysfs to get resource instance details for
a particular partition mode. A resource could be anything like an xcc,
vcn decoder, system dma units etc.
Details of various resource instances are available under
/sys/bus/pci/devices/.../compute_partition_config/
Select a partition configuration:
/sys/bus/pci/devices/.../compute_partition_config/xcp_config
Number of instances of a resource:
/sys/bus/pci/devices/.../compute_partition_config/<rsrc_name>/num_inst
Total partitions sharing the resource:
/sys/bus/pci/devices/.../compute_partition_config/<rsrc_name>/num_shared
v2: Update node name as per spec
