device/pci_rom: Rename missleading ON_DEVICE_ROM_RUN
The Kconfig option "ON_DEVICE_ROM_RUN" suggests that PCI Option ROMs
are run, but in fact it only controls the loading of PCI based
Option ROMs.
At the moment coreboot only executes Option ROMs if they are
VGA Options ROMs and the VGA Option ROM execution flag is enabled.
Setting ON_DEVICE_ROM_RUN with VGA Option ROM execution disabled
has no effect.
Clarify that this flag controls the loading behaviour and not the
execution behaviour.
