config: Update envs for trats and trats2 - Disable L2 cache
Disable L2 caches for Trats and Trats2 devices. It turns out that for data downloading with thordown command L2 cache disablement brings a significant speed improvement. rootfs - 400 MiB: - L2 cache enabled: 2.69 MiB/s - L2 cache disabled: 5.56 MiB/s Such improvement is possible due to reduction of the need to invalidate redundant data, which resides in L2 cache. Since the sent USB request size at once is 512B (L1 - 32 KiB in total) - one can be quite confident that it is already available in L1 and L2 can be disabled.
