Currently, we map the BAR spaces ahead of time and then match them with the capability they belong to. We can get the slot index from the capability and map the space based on that instead. Although creating a BAR list independent of the capability list could be useful for devices that do not support capability lists, we assume the existence of that support anyways. Fixes hermit-os#1392.
