Kernel/USB: Add a rudimentary interrogation only EHCI driver
This adds a simple EHCI driver that currently only interrogates the device and checks if all ports are addressable via associated legacy controllers (companion controllers), and warns if this is not the case. This also adds a lot of the other data structures needed for actually driving the controller, but these are currently not hooked up to anything. To test this run with `SERENITY_EXTRA_QEMU_ARGS="--device usb-ehci"` or the q35 machine type
