- one to copy in Linux 5.13's scripts/kconfig and adapt Makefile.inc

- adapt abuild to use olddefconfig, simplifying matters.
- apply patches in util/kconfig/patches.
- Some more adaptations to the libpayload build system.
The patches are now in util/kconfig/patches/, reverse applying them
should lead to a util/kconfig/ tree that contains exactly the Linux

This reverts commit ce0e2a0140 which was
originally introduced as a workaround for the bug that the Linux kernel
doesn't know what to do with type 16 memory region in the e820 table
where CBMEM resides and disallowed accessing it. After depthcharge was
patched to mark the type 16 region as a normal reserved region, the
Linux kernel now can access the BERT region and print BERT errors. When
SeaBIOS was used as payload it already marked the memory region
correctly, so it already worked in that case.
After commit 8c3a8df102 that removed the
usage of the BERT memory region reserved by the FSP driver by the AMD
Picasso and Cezanne SoCs and made them use CBMEM for the BERT region,
no other SoC code uses this functionality. The Intel Alderlake and
Tigerlake SoCs put the BERT region in CBMEM and never used this reserved
memory region and the change for the Intel server CPU to use this was
abandoned and never landed in upstream coreboot. AMD Stoneyridge is the
only other SoC/chipset that selects ACPI_BERT, but since it doesn't
select or use the FSP driver, it also won't be affected by this change.
