configuration registers directly.

Remove pci_enable_io calls where they are redundant. The PCI bus driver
will set the right bits when the corresponding bus resource is activated.

Remove redundant pci_* function calls from suspend/resume methods. The
bus driver already saves and restores the PCI configuration.
