aw_nmi: add support for a31/a83t's r_intc

We currently support the a83t's r_intc in a somewhat hack-ish way; our .dts
describes it as nmi_intc, and uses a subset of the actual register space to
make it line up with a20/a31 nmi offsets.

This breaks with the recent 4.14 update describing r_intc using the full
register space, so update aw_nmi to use the correct register offsets with
the right compat data in a way that doesn't break our current dts with
nmi_intc or upstream with r_intc described.

Fix SYSDIR path. After the move, we need to chop off a couple ../ from
the prior definition. But a safer definition is SRCTOP/sys, so use
that.

Inline pcie_link_{status,caps} where needed. Remove them as they
aren't really needed and I don't want to document them.

Use #if instead of #ifdef for __BSD_VISIBLE tests.

__BSD_VISIBLE is always defined and it's value instead needs to be
tested via #if to determine if FreeBSD-specific APIs should be
exposed.

Remove all fortune datfiles except freebsd-tips.

Humour is a funny thing. What is funny to one person is not funny to all
people. What is insightful to one person is similarly not universal. The
fortune datfiles have been around a long time and have undoubtedly amused
people but it's time to acknowledge their subjective, and in some cases
at least potentially offensive, nature and stop distributing them with the
imprimatur of the FreeBSD project.

If anyone wishes to distribute these via other mechanisms they are welcome to
check them out of history and do so.
