bnxt_en: Refactor ring reservation functions

The current functions to reserve hardware rings pass in 6 different ring
or resource types as parameters.  Add a structure bnxt_hw_rings to
consolidate all these parameters and pass the structure pointer instead
to these functions.  Add 2 related helper functions also.  This makes
the code cleaner and makes it easier to add new resources to be
reserved.
