Paolo Bonzini 15f07fb821 hw/usb: extract sysbus-ohci to a separate file
Split the sysbus version to a separate file so that it is not
included in PCI-only machines, and adjust Kconfig for machines
that do need sysbus-ohci.  The copyrights are based on the
time and employer of balrog and Paul Brook's contributions.

While adjusting the SM501 dependency, move it to the right place
instead of keeping it in the R4D machine.
