firewire: qualify config ROM cache pointers as const pointers
Several config ROM related functions only peek at the ROM cache; mark their arguments as const pointers. Ditto fw_device.config_rom and fw_unit.directory, as the memory behind them is meant to be write-once. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
