iwlwifi: size firmware flags memory correctly
Instead of relying on a hard-coded constant of a maximum of 64 API and
capability bits, add a new enum value after the others that will then
always track the number of used bits in the API/capabilities. We thus
no longer need to maintain the maximum number, and on 32-bit platforms
even (currently) reduce the number of bits kept in memory.
