soc/intel/broadwell: Add back support for EHCI debug setup

The EHCI debug device setup code was removed from broadwell in
    commit 49ee5ef: http://review.coreboot.org/11874

However the generic device setup code is in the southbridge/common/intel
    directory while broadwell is in the soc directory so this is not used.
    Add it back to the broadwell soc to fix undefined reference compile
    errors with 'pci_ehci_dbg_dev' and 'pci_ehci_dbg_enable'.

This was tested to compile and produce romstage and ramstage output on a
    google/samus board.
