So I've had a quick look about what could go possibly go away in our
current armv8 config (using the pine64+ defconfig). Let me know if
some are actually vitals:

- FIT_ENABLE_SHA256_SUPPORT
- CONSOLE_MUX
- CMD_CRC32
- CMD_LZMADEC
- CMD_UNZIP
- CMD_LOADB
- CMD_LOADS
- CMD_MISC (actually implementing the command sleep)
- ISO_PARTITION (yes. For CDROMs.)
- VIDEO_BPP8, VIDEO_BPP16
- VIDEO_ANSI
- SHA256
- LZMA

Removing those options make the u-boot.itb binary size going from
516kB to 478kB, making it functional again *and* allowing us to enable
the DT overlays that seem way more important than any feature
mentionned above (and bumps the size to 483kB).

Let me know what you think,
Maxime
