discover: Make boot_priorities more flexible
Rather than rely on the ordering of the boot_priorities array to define
which device types have a higher "default boot" priority, this change
introduces a slightly more flexible way of priority lookups, by adding a
separate priority field to struct boot_priority.
This means we can have an unordered array, change priorities without
re-writing the array, and implementing a disable mechanism.
