Add libfido2 to the build
From https://github.com/Yubico/libfido2:
libfido2 provides library functionality and command-line tools to
communicate with a FIDO device over USB, and to verify attestation
and assertion signatures.
libfido2 supports the FIDO U2F (CTAP 1) and FIDO 2.0 (CTAP 2)
protocols.
libfido2 will be used by ssh to support FIDO/U2F keys. It is currently
intended only for use by ssh, and so is installed as a PRIVATELIB and is
placed in the ssh pkgbase package.
This is currently disabled for the 32-bit library build as libfido2 is
not compatible with the COMPAT_32BIT hack in usb_ioctl.h.

Retire synchronous PPP kernel driver sppp(4).
The last two drivers that required sppp are cp(4) and ce(4).
These devices are still produced and can be purchased
at Cronyx <http://cronyx.ru/hardware/wan.html>.
Since Roman Kurakin <rik@FreeBSD.org> has quit them, they no
longer support FreeBSD officially. Later they have dropped
support for Linux drivers to. As of mid-2020 they don't even
have a developer to maintain their Windows driver. However,
their support verbally told me that they could provide aid to
a FreeBSD developer with documentaion in case if there appears
a new customer for their devices.
These drivers have a feature to not use sppp(4) and create an
interface, but instead expose the device as netgraph(4) node.
Then, you can attach ng_ppp(4) with help of ports/net/mpd5 on
top of the node and get your synchronous PPP. Alternatively
you can attach ng_frame_relay(4) or ng_cisco(4) for HDLC.
Actually, last time I used cp(4) back in 2004, using netgraph(4)
instead of sppp(4) was already the right way to do.
Thus, remove the sppp(4) related part of the drivers and enable
by default the negraph(4) part. Further maintenance of these
drivers in the tree shouldn't be a big deal.
While doing that, remove some cruft and enable cp(4) compilation
on amd64. The ce(4) for some unknown reason marks its internal
DDK functions with __attribute__ fastcall, which most likely is
safe to remove, but without hardware I'm not going to do that, so
ce(4) remains i386-only.

The non-scanning check further down assumes a frame format also not

happened because boot1 and loader were BE binaries trying to access
LE UFS partitions and because loader expects the kernel ELF image
to use the same endian as itself.
To fix these issues, boot1 and loader are now built as LE binaries
on PPC64LE. To support this, the functions that call OpenFirmware
were enhanced to correctly perform endian conversion on its input
