hw/usb/hcd-ehci: Fix crash when showing help of EHCI devices
QEMU crashes with certain targets when trying to show the help
output of EHCI devices:

$ ./qemu-system-aarch64 -device ich9-usb-ehci1,help
qemu-system-aarch64: ../../devel/qemu/softmmu/physmem.c:1154: phys_section_add:
 Assertion `map->sections_nb < TARGET_PAGE_SIZE' failed.
Aborted (core dumped)

This happens because the device is doing things at "instance_init" time
that should be done at "realize" time instead. So move the related code
to the realize() function instead. (NB: This now also matches the
memory_region_del_subregion() calls which are done in usb_ehci_unrealize(),
and not during finalize()).
