gnu: linux-libre: Support the Coreboot framebuffer.

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.

gnu/packages/aux-files/linux-libre/5.15-x86_64.conf:
Mark simple framebuffers as generic system ones and enable ‘Google’
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.
