[PATCH 02/11] PCI: Use Header Type in __pci_bridge_assign_resources()

["Ilpo Järvinen" <ilpo.jarvinen@linux.intel.com>]

Commit b2fb5cc57469 ("PCI: Rely on config space header type, not class
code") converted bridge window sizing and assignment to use the Header
Type but __pci_bridge_assign_resources() still uses the Class Code to
decide how to program the bridge windows. A Type 1 bridge whose Class
Code is not PCI_CLASS_BRIDGE_PCI gets its windows sized and assigned but
they are never programmed into the bridge.

Use the Header Type also in __pci_bridge_assign_resources().

I don't have known failure to point to with this, thus I've not added the
Fixes tag (the commit ref is available in the changelog if it's needed).
