…all intel boards touched in past commit

Touches c216, x230-flash, x230-legacy and x230-maximized.
TODO: Other boards, including AMD ones (qemu/kgpe) have this ON, including nv41/ns50 (which uses i915drm which most probably causes problems)
 Note that qemu boards use q35 in config, but were made to have both i440fx and q35, where q35 is tested, which explains why its on by default there.

- Move branding/Heads/bootsplash-1024x768.jpg -> branding/Heads/bootsplash.jpg (We don't care about the size. Make filename generic)
- Adapt all coreboot configs so bootsplash is adapted by BRAND_NAME CONFIG_BOOTSPLASH_FILE="@BRAND_DIR@/bootsplash.jpg"
  - Reminders :
    - Makefile changes Heads to defined BRAND_NAME in board config
    - Makefile changes -e 's!@BRAND_DIR@!$(pwd)/branding/$(BRAND_NAME)!g'
- nv41/nv50
  - coreboot oldefconfigs adapted by:
    - make BOARD=nitropad-ns50 coreboot.modify_and_save_oldconfig_in_place
    - make BOARD=nitropad-nv41 coreboot.modify_and_save_oldconfig_in_place
  - linux oldefconfigs adapted by
    - make BOARD=nitropad-nv41 linux.modify_and_save_oldconfig_in_place
      - since this is shared config across nv41/ns50: it only needs to be done for a single board
