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:
1dfe8c372163d481ebebb97dd3b4cafa49906b28 "gnu: linux-libre: Build simplefb into all x86{,_64} kernels."
bc09e7ab569d5306ce99c5525150695c9d539ef0 "gnu: linux-libre: Support the Coreboot framebuffer."

Fixes &lt;https://issues.guix.gnu.org/52667&gt; "System reconfiguration fails to build
linux-modules.drv".
