usbdebug: Drop duplicates of EHCI BAR relocation code
All the additional work that needs to be done in EHCI BAR relocation
is independent of the hardware platform and was functionally identical
in all the copies removed.
When USBDEBUG is not selected, PCI EHCI controllers use standard
pci_dev_read_resources() call.
With USBDEBUG selected, PCI EHCI controller's device_operations
.read_resources is replaced with pci_ehci_read_resources() call,
which in turn will replace the device_operations .set_resources call.
The replacement for .set_resources reconfigures usbdebug driver side,
and calls the original .set_resources to configure hardware side.
