HP iLO 4 BMC exposes its virtual keyboard via an internal UHCI USB controller (PCI 0000:01:00.4). Without uhci_hcd, this bus never initializes and the keyboard is invisible to the OS.

What? (description)
Enable
CONFIG_USB_UHCI_HCD=yin the amd64 kernel configuration.Why? (reasoning)
HP iLO 4 exposes its BMC Virtual Keyboard (03f0:7029) through an internal USB controller at PCI
0000:01:00.4. On Debian,uhci_hcdbinds to this controller and the keyboard enumerates atusb-0000:01:00.4-1/input0:$ ls -l /sys/bus/pci/devices/0000:01:00.4/driver lrwxrwxrwx 1 root root 0 Mar 11 22:11 /sys/bus/pci/devices/0000:01:00.4/driver -> ../../../../bus/pci/drivers/uhci_hcdThe Talos kernel has
ehci-hcdandxhci-hcdbuilt-in but does not includeuhci-hcdat all (neither built-in nor module). Without it, the iLO's USB controller never gets a driver, the BMC Virtual Keyboard never appears, and the Talos dashboard receives no keyboard input when accessed via iLO remote console.UHCI is Intel's USB 1.x host controller interface, only relevant on x86.
Fixes siderolabs/talos#12905
