cros_bundle_firmware: Add spl debug and vboot persist BL2 params

Add a parameter to control SPL debugging and the address of the vboot
persist region, also needed by SPL.

BUG=chrome-os-partner:21115
BRANCH=pit
TEST=manual
With U-Boot changes, see that SPL can locate and use the persist region.
Use:

crosfw -VFS -a '--add-config-int spl-debug 1'

and:

crosfw -VFS -a '--add-config-int spl-debug 0'

to check that debugging can be enabled/disabled.
