1. Get partition info/size
2. Erase partition
3. Flash partition
4. BCB
Make FASTBOOT_FLASH also depend on BLK, but make sure
it doesn't affect SUNXI and ROCKCHIP platforms since they
default to y already.
Make it only default on SUNXI when MMC or NAND is enabled,
so it doesn't break the CHIP & Nintendo boards, and for ROCKCHIP
when MMC is enabled.

Switch the mmc backend to this new shared block helpers,
reducing block logic and only leaving MMC specific logic.

Fastboot currently supports MMC and NAND flash devices. Similarly,
extend the support to SPI flash memories.
Note that in this initial implementation, partitions on the device are
not supported yet, but raw partitions can be set in U-Boot environment.
To define a raw partition descriptor, add an environment variable
similar to the MMC case:
```
fastboot_raw_partition_<raw partition name>=<offset> <size>
```
for example:
```
fastboot_raw_partition_boot=0x0 0x1000000
```

This reverts commit 0ebf9842e56c5b8cb7cb1f990bb452cc14af6225.
Current generic implementation of fastboot_set_reboot_flag is somewhat
messy and requires some additional configuration option to be enabled
besides CMD_BCB, so it reverts that implementtion in order to bring a
new cleaner one.
Next commit introduces new generic implementation of
fastboot_set_reboot_flag.

Default implementation of fastboot_set_reboot_flag function that depends
on "bcb" commands could be used in general case if there are no need to
make any platform-specific implementation, otherwise it could be
disabled via Kconfig option FASTBOOT_USE_BCB_SET_REBOOT_FLAG.
Please note that FASTBOOT_USE_BCB_SET_REBOOT_FLAG is mutually exclusive
with some platforms which already have their own implementation of this
function.

Ensure that when selecting FASTBOOT_FLASH you end up with a buildable
configuration. Prior to this you could select NAND without MTDPARTS
and end up with an image which (surprisingly) excluded NAND.
Also fix dependencies on FASTBOOT_GPT_NAME/FASTBOOT_MBR_NAME which require
you have EFI_PARTITION/DOS_PARTITION enabled.
Delete redundant FASTBOOT_FLASH_NAND_DEV from Kconfig - it was only ever
used as a guard and the value was ignored in all cases, we're using
FASTBOOT_FLASH_NAND as the guard now.

Add drivers/fastboot/fb_common.c, where fastboot_okay/fail are implemented
so we can call them from a non-USB implementation.
Introduce fastboot_response which takes varargs parameters so we can
use it to generate formatted response strings. Refactor fastboot_okay/fail
to use it.

Separate CMD_FASTBOOT from FASTBOOT and move code and configuration to
drivers/fastboot.
Switch dependencies on FASTBOOT to USB_FUNCTION_FASTBOOT as anyone who wants
FASTBOOT before this series wants USB_FUNCTION_FASTBOOT. Split
USB_FUNCTION_FASTBOOT from FASTBOOT so they retain their existing
behaviour.
