Control whether to build SVM support into amdgpu with a Kconfig option. This makes it easier to disable it in production kernels if this new feature causes problems in production environments. Use "depends on" instead of "select" for DEVICE_PRIVATE, as is recommended for visible options.

memory manager supports two modes of operation. One based on
