x86: broadwell: Don't bother probing the PCH for pinctrl

At present the pinctrl probes the PCH but since it only uses it to obtain
a PCI address, this is no necessary. Avoiding this fixes one of the two
co-dependent loops in broadwell.

This driver really should be a proper pinctrl driver, but for now it
remains a syscon device.
