PCI/portdrv: Declare support of movable BARs
Currently there are no reliable way to determine if a driver uses BARs of
its devices (their struct resource don't always have a child), so if it
doesn't explicitly support movable BARs, they are considered fixed.
The portdrv driver for PCI switches don't use BARs, so add a new hook
.bar_fixed() { return false; } to increase the chances to allocate new
BARs for new devices.
