src/default.nix: use a list of overlays rather than a single overlay
...
This commit changes from using a single overlay to using a
nixpkgs-like list of overlays chained together by
`lib.composeExtensions`.

kgpe: allow to configure recovery nvram values
...
On amd64 platforms, booting ownerboot with the recovery jumper
installed will wipe the battery-backed nvram (aka "cmos" aka "rtc
nvram") and overwrite it with known-safe values taken from the
coreboot source code (`src/mainboard/asus/kgpe-d16/cmos.default`).
You should always do this when flashing a motherboard with ownerboot
for the first time.
This commit allows the user to customize the set of known-safe
values which are written when the recovery jumper is installed. To
do so, copy `src/mainboard/asus/kgpe-d16/cmos.default` out of
coreboot, edit to suit your tastes, and then override
`cmos-defaults` with the path to your customized `cmos.default`
file.

kgpe: move microcode blob out of ownerboot
...
The microcode blob is only needed for Opteron 63xx chips. I have a
few of these, so I add the blob in a local overlay.
If other people are interested in this I will publish the overlay.
The 63xx chips are kind of rare and more expensive than the 62xx
chips -- their only real benefit is lower power draw. I ended up
receiving some by accident due to an incorrect eBay listing.

remove accidentally-checked-in file
...
I accidentally checked in "ectool-patches-of-unclear-provenance.patch",
which was never used in any way by the build expressions.
This file contained my local patches to a very old version of
ectool, some of which came from Debian and some of which I wrote
myself. The `ectool.nix` expression uses a newer version of ectool,
which has upstreamed the relevant changes from Debian. So those
patches no longer need to be carried. The other patches delete
functionality which I don't need, but other people might, so those
patches won't be included in ownerboot.

Relicense: GPL-v2-or-v3 instead of GPL-v2-or-later
...
At this point I am the only person who has contributed to ownerboot,
so I'm able to make this correction unilaterally. I wanted to do
this while I still had the chance.

kgpe/linux.config: remove sb700 watchdog-related settings
...
The KGPE-D16 southbridge contains a watchdog; the kernel module for
this watchdog is sp5100_tco.
Unfortunately this watchdog keeps its counter in the main system CPU
RAM. This means that the IOMMU will block the watchdog's attempts
to read and write its own counter (through the SMBus, which is PCI
device 0000:00:14.0), resulting in massive amounts of dmesg spam
like this:
```
pci 0000:00:14.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0004 address=0xfdf9103300 flags=0x0030]
piix4_smbus 0000:00:14.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0004 address=0xfdf9103300 flags=0x0030]
```
Setting the IOMMU to allow these accesses is a headache, and
pointless anyways: the KGPE-D16 board disallows the use of the
watchdog by the CPU; it is reserved for the exclusive use of the
BMC. Attempting to enable the watchdog does nothing; the enable bit
will not turn on. Recent kernels check for this situation and
report when it is detected:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f7781b067522aa269213e8025c80cbed1868d349
Fortunately there is *another* watchdog on the motherboard, inside
the `W83667HG-A` SuperIO chip, and it is supported by
`w83627hf_wdt.ko`. Subsequent commits to ownerboot will use *that*
watchdog instead.
