Support branding under branding subdirectories
Squash of #1502 + moving logo/bootsplash files under branding/Heads

- Move logos and bootsplashes from blobs to branding/Heads/
- Makefile: add support for BRAND_DIR which depends on BRAND_NAME which defaults to Heads if no branding
- Boards coreboot configs: change bootsplash directory to depend on BRAND_DIR (instead of BLOBS_DIR) in bootsplash enabled configs
- Branding/Heads/bootsplash-1024x768.jpg points to branding/Heads/d-wid-ThePlexus_coreboot-linuxboot-heads_background-plain_DonateQrCode.jpg
- xcf file deleted. Original still under #1502 to reuse for modification without recompressing (blobs/heads.xcf)
- CREDITS file created to point to original authors, remixers (Open for details)
  - Thanks to: @d-wid for remixing Bing's AI generated Janus logo, @ThePlexus for Qubes Box concept and @ThrillerAtPlay for its matrix background

coreboot configs: changeset needed to use efifb
- intel igpu related - remove i915drmfb hacks and use simplefb and libgfxinit enabled fb
- coreboot 4.19: add patch to fix https://ticket.coreboot.org/issues/500. fbwhiptail still tears screen if in native 1366x769 though
- coreboot 4.19: add patch to enable linux tampoline handle coreboot framebuffer (merged https://review.coreboot.org/c/coreboot/+/76431)
- coreboot 4.19: add patch to enable coreboot to apply jpeg voodoo to create bootsplash.jpeg injected in cbfs at build time + CircleCI apt imagemagick
  - (Thanks Nico Huber @icon again for above patches!)
- coreboot configs: adapt VESAFB/LIBGFXINIT to use maximum fb height/width
- coreboot configs for iGPU only: CONFIG_LINEAR_FRAMEBUFFER_MAX_HEIGHT CONFIG_LINEAR_FRAMEBUFFER_MAX_WIDTH to native size
- coreboot configs for dGPU based on Optional VBIOS injected: VESAFB set to 1280x1024 (maximum possible).

Details:
coreboot configs: remove CONFIG_LINUX_COMMAND_LINE="drm_kms_helper.drm_leak_fbdev_smem=1 i915.enable_fbc=0"
 - Those were needed to expose i915drmfb driver prior of efifb working.

Enable CONFIG_NO_GFX_INIT in coreboot on i915 boards with Linux 5.10
We don't need coreboot to initialize graphics on this boards, this
eliminates some unneeded code and the gnat dependency for them.

Coreboot was using libgfxinit, but it was initializing in text mode.
Heads' kernel will then switch to graphics mode, and we hand that
framebuffer from i915 to the target kernel during kexec.

t440p: Enable i915 kexec framebuffer fixes
Add CONFIG_DRM_FBDEV_LEAK_PHYS_SMEM and related kernel parameters to
t440p.  This board is already on kernel 5.10 and uses i915 graphics.

Add intel_iommu=igfx_off to T440p Coreboot kernel parameters
Without this, neither Qubes OS nor the Qubes OS installer would start.
Presumably, because we're "kexecing" from an already running kernel, we
need this set at the Coreboot level? Testing revealed that including
`intel_iommu=igfx_off` in the `CONFIG_BOOT_KERNEL_ADD` board config
option did nothing. And, the Qubes OS default boot option already
contains `intel_iommu=igfx_off`.

Adjust T440p default Coreboot defconfig options
Remove options that haven't deviated from defaults in the Coreboot
Kconfig, despite being saved by `make savedefconfig`. Also, add
`CONFIG_BOARD_LENOVO_THINKPAD_T440P`, which was missing from the `make
savedefconfig` output, causing Heads builds to fail. And finally, bump
`CONFIG_CBFS_SIZE` to `0x800000` (8 MiB to bytes to hexadecimal).

This value for the CBFS size is arbitrary. Originally, I had totaled the
size of all binary blobs, subtracted that from the T440p's ROM size (12
MiB), and used the remaining space as the CBFS size (~11.68 MiB).
However, this caused very long RAM initialization times (courtesy of
`cbmem -t`). And, an anecdote in
https://groups.google.com/a/chromium.org/g/chromium-os-reviews/c/lUqRrGUoEBY/m/ka7L1f2BS8gJ
suggested that this value needs to be a power of 2.

So, I picked a size I expected our Linux payload to fit into that was a
power of 2 that I also expected would leave enough space in the ROM for
the IFD, ME, GbE, and Coreboot.

Now, it takes less than a second for RAM initialization after
flashing/first boot (anecdotally, it seems the MRC needs to be
"trained?").

Add initial T440p Coreboot defconfig
I generated this config by walking through Coreboot's `make menuconfig`.
The plan is to pare down verbose defaults and tweak from here.
