i2c-designware-pci: Add Haswell ULT device IDs
From: Duncan Laurie <dlaurie@chromium.org>

Add the necessary PCI Device IDs to use the Haswell ULT
I2C controller in PCI mode.

Set the bus numbers to -1 so it will use dynamic assignment
rather than hardcoded.

i2c-designware-pci: Index Haswell ULT bus names from 0
Rather than having the bus names be "i2c-designware-pci--1" because
we have set the .bus_num to -1 to force dynamic allocation, lets have
the busses named "i2c-designware-pci-0" and "i2c-designware-pci-1"
to correspond to the correct names of these busses.

The adapter number will still be dynamically assigned.
