77dd0afe57 efi/uga: Fix PCIe LER when GRUB2 accesses non-enabled MMIO data from VGA 
A GPU inserted into a PCIe I/O slot disappears during system startup.
The problem centers around GRUB and a specific VGA init function in
efi_uga.c. This causes an LER (Link Error Recorvery) because the MMIO
memory has not been enabled before attempting access.

The fix is to add the same coding used in other VGA drivers, specifically
to add a check to insure that it is indeed a VGA controller. And then
enable the MMIO address space with the specific bits.

9ec5094213 coreboot: Split parts that are platform-independent. 
We currently assume that coreboot is always i386, it's no longer the case,
so split i386-coreboot parts from generic coreboot code.

4bd4a88725 i386, x86_64, ppc: fix switch fallthrough cases with GCC7 
In util/getroot and efidisk slightly modify exitsing comment to mostly
retain it but still make GCC7 compliant with respect to fall through
annotation.

In grub-core/lib/xzembed/xz_dec_lzma2.c it adds same comments as
upstream.

In grub-core/tests/setjmp_tets.c declare functions as "noreturn" to
suppress GCC7 warning.

In grub-core/gnulib/regexec.c use new __attribute__, because existing
annotation is not recognized by GCC7 parser (which requires that comment
immediately precedes case statement).

Otherwise add FALLTHROUGH comment.

Closes: 50598
