Jacob Pan 253d2e5498 PCI: disable mmio during bar sizing
It is a known issue that mmio decoding shall be disabled while doing PCI
bar sizing. Host bridge and other devices (PCI PIC) shall be excluded for
certain platforms. This patch mainly comes from Mathew Willcox's
patch in http://kerneltrap.org/mailarchive/linux-kernel/2007/9/13/258969.

A new flag bit "mmio_alway_on" is added to pci_dev with the intention that
devices with their mmio decoding cannot be disabled during BAR sizing shall
have this bit set, preferrablly in their quirks.

Without this patch, Intel Moorestown platform graphics unit will be
corrupted during bar sizing activities.
