Use __raw_{read,write}l accessors and use Abort interrupt to detect a
configuration space read/write errors. The second change improves errors
detection, what improves the device presence detection and helps us to
avoid following (and similar) errors:
pci 0000:00:00.2: ignoring class 0x7e0200 (doesn't match header type 02)
pci 0000:00:00.2: bridge configuration invalid ([bus 03-90]), reconfiguring
pci 0000:00:00.2: not setting up bridge for bus 0000:01

Add PCI IRQ controller to facilitate interrupt handling, move interrupts
initialization to the IRQ controller initialization from
pcibios_plat_dev_init() callback.
Also remove odd PCI dev configuration manipulation from pcibios_plat_dev_init()
callback.

Explicitly configure PCI host controller, and do not expose it to PCI
subsystem. The PCI host controller acts as a usual PCI device connected
to the bus, but its configuration as a usual PCI device is senseless,
since the host controller provide access to _internal_ memory space for
_external_ device.
