b9c99d3246 usb: dfu: thor: gadget: Remove dead code
This code is not used anymore in the current DFU implementation and
can be safely removed.

7ac1b410ac dfu: allow backend to specify a maximum buffer size
CONFIG_SYS_DFU_DATA_BUF_SIZE may be large to allow for FAT/ext layouts
to transfer large files. However, this means that individual write
operations will take a long time. Allow backends to specify a maximum
buffer size, so that each write operation is limited to a smaller data
block. This prevents the DFU protocol from timing out when e.g. writing
to SPI flash. I would guess that NAND might benefit from setting this
value too, but I can't test that.

19a2a67fa2 usb:g_dnl:f_thor: remove memset before memcpy
since ALLOC_CACHE_ALIGN_BUFFER defines a pointer and not a
buffer, the memset with sizeof(rqt) likely does something else
then intended. Since there is a memcpy directly after it with
the full size, drop the memset completely.

584b55b072 usb:gadget:f_thor: download_tail(): remove dfu_write with 0 size
Since dfu_flush() can write raw data, dfu_write() with zero size
can be removed from download_tail() in thor gadget.

c4d0e85604 USB: gadget: added a saner gadget downloader registration API
Preprocessor definitions and hardcoded implementation selection in
g_dnl core were replaced by a linker list made of (usb_function_name,
bind_callback) pairs.

fd2a89b20b usb:gadget:f_thor: fix write to filesystem by add dfu_flush()
Since dfu read/write operations needs to be flushed manually,
writing to filesystem on MMC by thor was broken. MMC raw write
actually is working fine because current dfu_flush() function
writes filesystem only. This commit adds dfu_flush() to f_thor
and now filesystem write is working.

This change was tested on Trats2 board.

adfc17bf09 usb:gadget:f_thor: code cleanup in function download_tail()
In thor's download_tail() function, dfu_get_entity() is called
before each dfu_write() call and the returned entity pointers
are the same. So dfu_get_entity() can be called just once and
this patch changes this.

Apparently debug memset (with a 0x55 value) has been overlooked in the

the host (OUT transaction) to the size of THOR packet.
