Add function to respond to fastboot flash and erase. Flash writes the
previously downloaded image to indicated partition. Erase clears the
indicated partition. fb_flash and fb_erase are essentially wrappers
for fb_mmc_flash_write and fb_mmc_erase, which are implemented in
common/fb_mmc.c.
Added common/fb_common.c, where fastboot_okay/fail are implemented.
common/fb_mmc.c assumes fasboot_okay() and fastboot_fail() are
implemented, but they were tied to the fastboot USB implementation.
This refactor adds the response string as a parameter to
fastboot_okay/fail, instead of modifying a global.
Bug: 31887729
Test: FLASH:
- Create file "foo" containing 2048 chars = "-"
- Start "fastboot udp" on device and run
"fastboot -s udp:$RPI_IP flash misc foo" from host
- From U-boot console, read into memory the first 4 blocks from
misc partition, observe each byte is "-".
ERASE
- Start "fastboot udp" on device and run
"fastboot -s udp:$RPI_IP erase misc" from host
- From U-boot console, read into memory many blocks from misc
partition, observe each byte is 0x00
Configs that use fastboot USB implementation still build.

In order to process the CHUNK_TYPE_DONT_CARE properly, there is
a requirement to be able to 'reserve' a specified number of blocks
in the storage media. Because of the special handling of "bad blocks"
in NAND devices, this is implemented in a storage abstraction function.

- update fastboot_okay() and fastboot_fail()
This file originally came from upstream code.
While retaining the storage abstraction feature, this is the second
set of the changes required to resync with the
cmd_flash_mmc_sparse_img()
in the file
aboot.c
from
https://us.codeaurora.org/cgit/quic/la/kernel/lk/plain/app/aboot/aboot.c?h=LE.BR.1.2.1

This "session-id" alogrithm is not required, and currently corrupts
the stored image whenever more the one "session" is required.

The Android sparse image format is currently supported through a file
called aboot, which isn't really such a great name, since the sparse image
format is only used for transferring data with fastboot.
Rename the file and header to a file called "sparse", which also makes it
consistent with the header defining the image structures.
