coreboot-librem*: Set framebuffer kernel params for Librems except L1UM

JonathonHall-Purism · JonathonHall-Purism · commit cd4c1a0fdb64 · 2023-04-19T10:32:23.000-04:00
Allow leaking the DRM framebuffer pointer to userspace, and disable
framebuffer compression, like librem_15v4.

Tested booting memtest86+ and Debian netinstaller on Mini v2.

Do not enable this for L1UM, it uses Aspeed graphics which still don't
work.  qemu uses virtio graphics, which also are not working.
