Update Purism coreboot to 24.02.01-Purism-1.
Remove CFLAGS overrides when building coreboot. These overrides break
24.02.01, which added (and needs) --param=min-pagesize=1024. This has
happened repeatedly in the past since Heads has to duplicate coreboot's
CFLAGS if it overrides them.
Specifically, the build fails with this error:
src/commonlib/include/commonlib/endian.h:27:26: error: array subscript 1 is outside array bounds of 'void[0]' [-Werror=array-bounds=]
27 | *(uint8_t *)dest = val;
| ~~~~~~~~~~~~~~~~~^~~~~
In function 'setup_default_ebda':
cc1: note: source object is likely at address zero
That's because coreboot is attempting to write to EBDA at physical
address 0x40e, just above 1024. That is a valid address for x86, but
it's too close to 0 by default for GCC, --param-min-pagesize=1024
allows writes to physical addresses above 1024.
coreboot shouldn't need any of the usual Heads CFLAGS overrides for
reproducibility; it is already reproducible.
Fix indentation in modules/coreboot. Make accepted it before because
the indented lines followed a variable assignment, so they couldn't
be part of a recipe. That assignment is now gone, so they're now
interprted as part of a recipe for the `.configured` target just above,
they should not be indented.
Add nss to flake.nix, needed as of 24.02.01.
Update Librem coreboot configs for 24.02.01-Purism-1. Notably, the
board Kconfig changed for Mini v2 in coreboot, so this is needed for
correct builds.

Update all Librems except L1UM (but including L1UM v2) to Linux 6.1.8.
Use coreboot native graphics init. Raise maximum framebuffer size for
laptops to 3840x2160 (desktops default to this, but laptops default
to a lower value). Remove DRM modules from Linux 6.1.8 and add EFIFB.
Remove Heads kernel command line options relating to IOMMU and i915,
which are no longer needed. Remove OS kernel options relating to
IOMMU.
For Librem 13/15/14/Mini, this fixes issues booting with 4K displays
attached, which were resulting in crashes due to the framebuffer memory
not being reserved properly. memtest86+ now passes with a 4K display
attached.
For Librem L1UM v2, framebuffer boot now works.
Librem L1UM remains on Linux 5.10 with Heads kernel graphic init
(framebuffer boot still does not work). coreboot 4.11 has native
graphics init for Aspeed, but only in text mode. Backporting the
linear framebuffer support appears to be possible - the patch applied
cleanly - but it did not work initially and will need more
investigation.
