wii: Add support for GameCube controller sockets.

A new driver is introduced for the Serial Interface that exposes the four
GameCube controller sockets as uhid(4) devices. The report format and HID
usages of these devices attempts to mimic the official USB GameCube
controller adapter.

Enable PaX features in WII kernel configuration.

Seems to work fine, with mmap addresses being randomized per-process
and (PROT_WRITE | PROT_EXEC) resulting in a segfault.

wii: Add support for using a USB Gecko as serial console.

The USB Gecko is a Wii/Gamecube development tool which connects to the
GameCube memory slot of the Wii and a USB port of a computer. The USB
port exposes an FTDI serial port on the computer side of the connection.

EXI commands sent from the Wii to the USB Gecko can read and write bytes.
Wire this up to form a simple serial console when the device is detected.
Use WSDISPLAY_MULTICONS to allow for simultaneous use of the USB Gecko
and the framebuffer console.

wii: Add support for hardware AES engine and cgd(4) to the WII kernel.

Add a driver for the Nintendo Wii's AES engine. The driver registers an
AES implementation for kernel use via aes_md_init(). AES-128 requests are
accelerated by hardware and all other requests are passed through to the
default (BearSSL aes_ct) implementation.

Add cgd(4) to the Wii kernel to enable disk encryption support.

Tested performance with cgd(4) and AES-128-CBC on a USB flash drive:

hwaes: 33513984 bytes transferred in 2.245 secs (14928277 bytes/sec)
bear: 33513984 bytes transferred in 7.581 secs (4420786 bytes/sec)

Many thanks to Taylor Campbell who walked me through implementing support
for non-CBC modes.

branches: 1.9.2;
wii: Remove some options to save memory.

wii: Add support for Wii DVD drive.

This adds a virtual SCSI HBA driver that is able to read DVD video discs
inserted in the Wii.

bwi(4): Add support for Nintendo Wii WLAN.

Adapt the bwi(4) driver to support SDIO attachment and driving TX/RX using
PIO instead of DMA since the latter is not supported on SDIO busses.

wii: Enable ohci(4) driver.

This seems to be stable now, let's enable support for plugging in LS/FS
devices directly into the system without a hub.
