The GPIO controls the multiplexing of the D1 pins to its peripherals,
so this adds the definitions needed by the aw_gpio driver to support
the D1.

Also, this modifies the aw_gpio driver to support the differences of
the D1 controller:

- pins can have up to 15 functions
- each port is mapped with an alignment of 0x30
- CFG registers have 4 bits per pin
- DRV registers have 4 bits per pin
- the offset of PULL registers is 0x24

sys: add conf/std.debug, generic debugging options

The new sys/conf/std.debug contains the list of debugging options
enabled by default in -CURRENT, so they don't need to be listed
individually in every kernel config.

The enabled options are the set of all debug options which were enabled
for the GENERIC kernel on any platform. This means some architectures
now have debugging options enabled in GENERIC which weren't previously
enabled:

- amd64: [1]
- arm64: [2]
- arm: [2]. [3]
- i386: [1], [2]
- powerpc: [1], [2], [3]
- riscv: [2]

[1] ALT_BREAK_TO_DEBUGGER is now enabled.
[2] BUF_TRACKING, FULL_BUF_TRACKING, and QUEUE_MACRO_DEBUG_TRASH are now
enabled.
[3] DEADLKRES is now enabled.

While here, move the documentation for the (commented out) K*SAN options
for amd64 from GENERIC to NOTES.

netlink: add NETLINK to the DEFAULTS for each architecture

NETLINK is going to replace rtsock and a number of other ioctl/sysctl interfaces.
In-base utilies such as route(8), netstat(8) and soon ifconfig(8)
are being converted to use netlink sockets as a transport between
kernel and userland.
In the current configuration, it still possible have the kernel
without NETLINK (`nooptions NETLINK`) and use the aforementioned
utilies by buidling the world with `WITHOUT_NETLINK` src.conf knob.
However, this approach does not cover the cases when person unintentionally
builds a custom kernel without netlink and tries to use the standard userland.

This change adds `option NETLINK` to the default options for each
architecture, fixing the custom kernel issue.
For arm, this change uses `std.armv6` and `std.armv7` (netlink already in)
instead of DEFAULTS.

netlink: add NETLINK to GENERIC.

This is a followup of 692e19cf5195 (add netlink to GENERIC@amd64).

Netlink is a communication protocol defined in RFC 3549. It is async,
TLV-based protocol, providing 1-1 and 1-many communications between kernel
and userland. Netlink is currently used in Linux kernel to modify, read and
subscribe for nearly all networking states. Interface state, addresses, routes,
firewall, rules, fibs, etc, are controlled via Netlink.

Netlink support was added in D36002. It has got a number of improvements and
first customers since then:
* net/bird2 got netlink support, enabling route multipath in FreeBSD
* netlink-based devd notifications are being worked on ( D37574 ).
* linux(4) fully supports and depends on Netlink

Enabling Netlink in GENERIC targets two goals.
The first one is to provide stability for the third-party userland applications,
so they can rely on the fact that netlink always exists since 14.0 and potentially 13.2.
Loadable module makes life of the app delepers harder. For example, `net/bird2` can be
either build with netlink or rtsock support, but not both.

The second goal is to enable gradual conversion of the base userland tools
to use netlink(4) interfaces. Converting tools like netstat (D36529), route,
ifconfig one-by-one simplifies testing and addressing the feedback.
Othewise, switching all base to use netlink at once may be too big of a leap.
