test/py: add DFU test

Add a test of DFU functionality to the Python test suite. The test
starts DFU in U-Boot, waits for USB device enumeration on the host,
executes dfu-util multiple times to test various transfer sizes, many
of which trigger USB driver edge cases, and finally aborts the DFU
command in U-Boot.

This test mirrors the functionality previously available via the shell
scripts in test/dfu, and hence those are removed too.

-DFU TEST CASE DESCRIPTION:
-
-The prerequisites for running this script are assured by
-dfu_gadget_test_init.sh, which is automatically invoked by dfu_gadget_test.sh.
-In this file user is able to generate their own set of test files by altering
-the default set of TEST_FILES_SIZES variable.
-The dfu_gadget_test_init.sh would generate test images only if they are not
-already generated.
-
-On the target device, environment variable "dfu_alt_info" must contain at
-least:
-
-    dfu_test.bin fat 0 6;dfudummy.bin fat 0 6
-
-Depending on your device, you may need to replace "fat" with
-"ext4", and "6" with the relevant partition number. For reference please
-consult the config file for TRATS/TRATS2 devices
-(../../include/configs/trats{2}.h)
-
-One can use fat, ext4 or any other supported file system supported by U-Boot.
-These can be created by exporting storage devices via UMS (ums 0 mmc 0) and
-using standard tools on host (like mkfs.ext4).
-
-Example usage:
-1. On the target:
-   setenv dfu_alt_info dfu_test.bin fat 0 6\;dfudummy.bin fat 0 6
-   dfu 0 mmc 0
-2. On the host:
-   test/dfu/dfu_gadget_test.sh X Y [test file name] [usb device vendor:product]
-   e.g. test/dfu/dfu_gadget_test.sh 0 1
-   or
-   e.g. test/dfu/dfu_gadget_test.sh 0 1 ./dat_960.img
-   or
-   e.g. test/dfu/dfu_gadget_test.sh 0 1 0451:d022
-   or
-   e.g. test/dfu/dfu_gadget_test.sh 0 1 ./dat_960.img 0451:d022
-
-... where X and Y are dfu_test.bin's and dfudummy.bin's alt setting numbers.
-They can be obtained from dfu-util -l or $dfu_alt_info.
-It is also possible to pass optional [test file name] to force the script to
-test one particular file.
-If many DFU devices are connected, it may be useful to filter on USB
-vendor/product ID (0451:d022).
-One can get them by running "lsusb" command on a host PC.
