Since the introduction of 'soft-rc6', we aim to park the device quickly and that results in frequent idling of the whole device. Currently upon idling we free the batch buffer pool, and so this renders the cache ineffective for many workloads. If we want to have an effective cache of recently allocated buffers available for reuse, we need to decouple that cache from the engine powermanagement and make it timer based. As there is no reason then to keep it within the engine (where it once made retirement order easier to track), we can move it up the hierarchy to the owner of the memory allocations. v2: Hook up to debugfs/drop_caches to clear the cache on demand.
