PCI: Disable non-claimed bridge window
If clipping or claiming the bridge window fails, the bridge window is left
in a state that does not match the kernel's view on what the bridge window
is.
Disable the bridge window by writing the magic disable value into the Base
and Limit Registers if clipping or claiming failed. To detect if claiming
the resource was successful, add res->parent checks into the bridge setup
functions.
