drm/i915: Fix PCH detect with multiple ISA bridges in VM

In some virtualized environments (e.g. XEN), there is irrelevant ISA bridge in
the system. To work reliably, we should scan trhough all the ISA bridge
devices and check for the first match, instead of only checking the first one.

subsystem header to the commit message headline.]
