cmem-mod: Remove CMEM kernel module
CMEM has been deprecated for removal for some time now. All users should have migrated to the Linux upstream DMA-BUF Heaps framework. Remove CMEM. We only remove the kernel module part in this patch to prevent builds from breaking in the meta-arago layer due to dependencies on the CMEM library. These packages should either be updated or disabled. After that we will remove the library.
