067c13c70b dfu: add callback for flush and initiated operation
Add weak callback to allow board specific behavior
- flush
- initiated

This patch prepare usage of DFU back end for communication with
STM32CubeProgrammer on stm32mp1 platform with stm32prog command.

d5640f700d dfu: add partition support for MTD backend
Add the support of MTD partition for the MTD backend.

The expected dfu_alt_info for one alternate on the mtd device :
	<name> part <part_id>
        <name> partubi <part_id>

"partubi" also erase up to the end of the partition after write operation.

For example: dfu_alt_info = "spl part 1;u-boot part 2; UBI partubi 3"

U-Boot> dfu 0 mtd nand0

6015af28ee dfu: add backend for MTD device
Add DFU backend for MTD device: allow to read
and write on all MTD device (NAND, SPI-NOR,
SPI-NAND,...)

For example :
> set dfu_alt_info "nand_raw raw 0x0 0x100000"
> dfu 0 mtd nand0

This MTD backend provides the same level than dfu nand
backend for NAND and dfu sf backend for SPI-NOR;
So it can replace booth of them but it also
add support of spi-nand.

> set dfu_alt_info "nand_raw raw 0x0 0x100000"
> dfu 0 mtd spi-nand0

The backend code is based on the "mtd" command
introduced by commit 5db66b3aee ("cmd: mtd:
add 'mtd' command")

febabe3ed4 dfu: allow to manage DFU on several devices
Add support of DFU for several interface/device
with one command.

The format for "dfu_alt_info" in this case is :
- <interface> <dev>'='alternate list (';' separated)
- each interface is separated by '&'

The previous behavior is always supported.

One example for NOR (bootloaders) + NAND (rootfs in UBI):

U-Boot> env set dfu_alt_info \
"sf 0:0:10000000:0=spl part 0 1;u-boot part 0 2; \
u-boot-env part 0 3&nand 0=UBI partubi 0,3"

U-Boot> dfu 0 list

DFU alt settings list:
dev: SF alt: 0 name: spl layout: RAW_ADDR
dev: SF alt: 1 name: ssbl layout: RAW_ADDR
dev: SF alt: 2 name: u-boot-env layout: RAW_ADDR
dev: NAND alt: 3 name: UBI layout: RAW_ADDR

U-Boot> dfu 0

$> dfu-util -l

Found DFU: [0483:5720] ver=9999, devnum=96, cfg=1,\
 intf=0, alt=3, name="UBI", serial="002700333338511934383330"

cb986ba0fe dfu: sf: add partition support for nor backend
Copy the partition support from NAND backend to SF,
support part and partubi option.
In case of ubi partition, erase the rest of the
partition as it is mandatory for UBI.

The added code is under compilation flag CONFIG_DFU_SF_PART
activated by default.

for example:

U-Boot> env set dfu_alt_info "spl part 0 1;\
u-boot part 0 2;u-boot-env part 0 3;UBI partubi 0 4"
U-Boot> dfu 0 sf 0:0:10000000:0
