cros_bundle_firmware: Make u-boot and bmpblk optional

These two parameters are not always required, so can be made optional.
This change is required by the new cros_write_firmware which doesn't
actually have a U-Boot or bmpblk.

BUG=chromium-os:17298
TEST=run new cros_write_firmware, check that it runs OK without these parameters
