Use the uthread framework to initialize and scan USB buses in parallel
for better performance. The console output is slightly modified with a
final per-bus report of the number of devices found, common to UTHREAD
and !UTHREAD. The USB tests are updated accordingly.
Tested on two platforms:
1. arm64 QEMU on a somewhat contrived example (4 USB buses, each with
one audio device, one keyboard, one mouse and one tablet)
$ make qemu_arm64_defconfig
$ make -j$(nproc) CROSS_COMPILE="ccache aarch64-linux-gnu-"
$ qemu-system-aarch64 -M virt -nographic -cpu max -bios u-boot.bin \
$(for i in {1..4}; do echo -device qemu-xhci,id=xhci$i \
-device\ usb-{audio,kbd,mouse,tablet},bus=xhci$i.0; \
done)
2. i.MX93 EVK (imx93_11x11_evk_defconfig) with two USB hubs, each with
one webcam and one ethernet adapter, resulting in the following device
tree:
USB device tree:
1 Hub (480 Mb/s, 0mA)
| u-boot EHCI Host Controller
|
+-2 Hub (480 Mb/s, 100mA)
| GenesysLogic USB2.1 Hub
|
+-3 Vendor specific (480 Mb/s, 350mA)
| Realtek USB 10/100/1000 LAN 001000001

Note that i.MX was tested on top of the downstream repository [1] since
USB doesn't work in the upstream master branch.

The time spent in usb_init() ("usb start" command) is reported on
the console. Here are the results:
| CONFIG_UTHREAD=n | CONFIG_UTHREAD=y
--------+------------------+-----------------
QEMU | 5628 ms | 2212 ms
i.MX93 | 4591 ms | 2441 ms
