The command register of the PCI controller is
not initialized correctly by the bootloader on
some boards and this leads to non working PCI
bus.

Add code to initialize the command register
from the Linux code to avoid this.

Static resources become impractical when multiple

The current code uses static variables to store the
PCI controller specific data. This works if the system
contains one PCI controller only, however it becomes
impractical when multiple PCI controllers are present.

Move the variables into a dynamically allocated controller
specific structure, and use that instead of the static
variables.

The pci_load_of_ranges function is only available if

The IO and memory resources of a PCI controller
might already have a parent resource set when
they are passed to 'register_pci_controller'.

If the parent resource is set, the request_resource
call will fail due to resource conflict and the
current code will not be able to register the
PCI controller.

Use the parent resource if it is available in the
request_resource call to avoid the isssue.
