These changes broke the creation of the 'linux-modules-database' for all kernel
series besides 5.15, 5.4, and 5.10, like this:
------
gnu/build/linux-modules.scm:257:5: kernel module not found "framebuffer_coreboot" "/gnu/store/yff45fr6q93mw44zdql9ffr95zcvwxcn-linux-libre-4.9.299/lib/modules"
------
We should support the coreboot framebuffer, but we need to test that change more
completely before deploying it.
This effectively reverts the following commits:
1dfe8c3721 "gnu: linux-libre: Build simplefb into all x86{,_64} kernels."
bc09e7ab56 "gnu: linux-libre: Support the Coreboot framebuffer."
Fixes <https://issues.guix.gnu.org/52667> "System reconfiguration fails to build
linux-modules.drv".
Without this, the kernel cannot write to the display until the
full-featured driver module (often i915) is loaded from the root file
system.
If the root file system is encrypted, the initrd's passphrase prompt
won't make it to the screen, and the fully responsive system will appear
frozen whilst waiting for user input.

firmware drivers to enable Coreboot table support and its dependent
framebuffer driver module.
* gnu/system/linux-initrd.scm (default-initrd-modules):
Add the framebuffer_coreboot and simplefb modules on x86 systems.

Add the 32x16 Terminus font for ‘high-DPI’ screens, and a 6x10 font that
allows for more (debugging) information to be displayed on standard-DPI
ones, while still being pleasant to read.
