usb: dfu: Migrate CONFIG_SYS_DFU_DATA_BUF_SIZE and CONFIG_SYS_DFU_MAX_FILE_SIZE to Kconfig
Currently the config options CONFIG_SYS_DFU_DATA_BUF_SIZE and
CONFIG_SYS_DFU_MAX_FILE_SIZE are being set in include/configs/<board>.h
files and also in <board_name>_defconfig files without a Kconfig option. It
is easier for users to set these configs in defconfig files than in config
header files as they are a part of the source code.
Add Kconfig symbols, and update the defconfigs by using tools/moveconfig.py
script.

This option allows to call the function set_dfu_alt_info to
dynamically build dfu_alt_info in board.

+ hex "Size of buffer to be allocated for transfer to raw storage device"
+ default 0x800000
+ help
+ DFU transfer uses a buffer before writing data to the
+ raw storage device. This value can be used for setting the
+ size of this buffer. The size of the buffer is also configurable
+ through the "dfu_bufsiz" environment variable. If both are
+ given the size of the buffer is set to "dfu_bufsize".
+
+config SYS_DFU_MAX_FILE_SIZE
+ hex "Size of the buffer to be allocated for transferring files"
+ default SYS_DFU_DATA_BUF_SIZE
+ help
+ When updating files rather than the raw storage device,
+ we use a static buffer to copy the file into and then write
+ the buffer once we've been given the whole file. Define
+ this to the maximum filesize (in bytes) for the buffer.
+ If undefined it defaults to the CONFIG_SYS_DFU_DATA_BUF_SIZE.
