atomisp: use type 1 instead of message bus for PCI config space access.

atomisp: use type 1 instead of message bus for PCI config space access.

BZ: 2243

We need use type 1 standard PCI config space access for real
PCI devices in Penwell Soc. These devices are 0:0:0(host bridge),
0:2:0(graphics) and 0:3:0(ISP).

The original codes in arch/x86/pci/mrst.c missed the ISP device
(00:03.0) from type 1 device white list. This patch fixes it.
