cxl/core: Drop ->platform_res attribute for root decoders
Root decoders are responsible for hosting the available host address
space for endpoints and regions to claim. The tracking of that available
capacity can be done in iomem_resource directly. As a result, root
decoders no longer need to host their own resource tree. The
current ->platform_res attribute was added prematurely.
Otherwise, ->hpa_range fills the role of conveying the current decode
range of the decoder.
