PCI: Use pci_release_resource() instead of release_resource()

Browse source

A few places in setup-bus.c call release_resource() directly and end up
duplicating functionality from pci_release_resource() such as parent check,
logging, and clearing the resource. Worse yet, the way the resource is
cleared is inconsistent between different sites.

Convert release_resource() calls into pci_release_resource() to remove code
duplication. This will also make the resource start, end, and flags
behavior consistent, i.e., start address is cleared, and only
IORESOURCE_UNSET is asserted for the resource.

While at it, eliminate the unnecessary initialization of idx variable in
pci_bridge_release_resources().
