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.

This patch adds extra dfu_alt_info entries to support storing the whole BOOT
, DATA and UMS partitions.
This allows upgrade of uImage and device tree blob (dtb) files at once.
Now it is also possible to store ext4 rootfs prepared with well established
linux tools (like mkfs.ext4).
