usbhost: refactor the initialization

Before that, drivers had to setup MMIO range multiple times, or even parse hw
resources themselves again. The former init method was split in half - init and
start. Init shall allocate and initialize inner structures, start shall start
the HC.

In the XHCI it is demonstrated how to isolate inner HC implementation from the
fact this driver is using libusbhost. It adds some boilerplate code, but
I think it leads to cleaner design.
