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.

Compressed framebuffer requires the driver to track updates to the
framebuffer from the CPU and update the compressed framebuffer. This
doesn't work if we kexec into an OS that will use the linear
framebuffer, so disable it. (The OS kernel can still use compressed
framebuffer if it has i915.)
Linux 5.8 enabled compressed framebuffer on more chipsets using i915,
which is why this stopped working.
memtest86+ and Debian (manually blacklisted i915, comparable to
netinst) now boot correctly on Librem 15v4. This will need to be
enabled for other boards too.

kexec(8) needs to get the framebuffer address in order to set up the
new kernel's boot parameters. This is one of the reasons that using a
>4.20 kernel in Heads prevents framebuffer graphics from working in the
OS kernel.
Linux 4.20 started hiding this address from userspace, because
userspace is not supposed to need physical memory addresses. A
workaround was added to keep leaking the address, apparently for some
proprietary userspace OpenGL drivers. This requires both a Kconfig and
a kernel parameter.
This commit enables the Kconfig on the librem_common config, and the
kernel parameter on the librem_15v4 (where I'm testing this). We will
need to enable it on other >4.20 configs/boards as well.

This makes configs much less dependent on directory layout.
As of this commit the following variables are supported:
* @BOARD_BUILD_DIR@ - absolute path under build/
* @BLOB_DIR@ - absolute path to blobs/

Update all Purism Librem boards except the L1UM server
to coreboot 4.15:
- update coreboot version from 4.8.1/4.13 to 4.15
- use purism_blobs module (if not already)
- update board coreboot defconfig files (Librem 13/15)

Set the kernel video mode for the internal display to 1080p,
as the native panel resolution of 2160p is difficult to read.
A recent update to fbwhiptail allows the GUI to make use of the
scaled resolution as well, provided it is set via kernel param.

* modules: add purism-blobs module
Rather than require users to manually run a script to download the required
blobs to build Purism Librem boards, automate it so the correct version
is automatically downloaded/extracted. Restrict to coreboot 4.12 for now
since 4.8.1 still needs FSP blobs, which are not in module.
