iwlwifi: prepare for higher API/CAPA bits
Currently, loading the firmware fails when it has higher API or CAPA bits than the driver supports. That's an issue with integration. At the same time, actually using api[0] and capa[0] will become confusing when we also have api[1] and capa[1], and it's almost certain that we'll mix up the bits and use the bits for api[1] with api[0] by accident. Avoid all this by translating the API/CAPA bits to the regular kernel test_bit() format, and also providing wrapper functions. Also use the __bitwise__ facility of sparse to check that we're testing the right one.
