Adds ability to send trim commands to FTL - only 4MiB aligned requests (both for offset and length of request) will be processed. During a trim operation an L2P page (containing 1024 4B entries, 1 per user LBA; which is where the 4MiB alignment comes from) will be marked as unmapped. After this point any L2P access to that page will actually set the entries themselves as FTL_ADDR_INVALID. This is done to make the trim as fast as possible, since for large requests it's probable that most of the L2P pages aren't actually in DRAM.
