The Local Memory Translation Table (LMTT) provides additional abstraction for Virtual Functions (VF) accessing device VRAM. This code is based on prior work of Michal Winiarski. In this patch we focus only on LMTT initialization. Remaining LMTT functions will be used once we add a VF provisioning to the PF.
