net/bnxt: update HWRM ring related structures

Update the PMD to use HWRM ring related structures as per the 1.5.1
version of the HWRM API.  Most of the changes in the patch are white
spaces and rearrangement of the lines - a onetime change owing to the
usage of a different auto generated file.

Structures being updated:
hwrm_ring_alloc_input, hwrm_ring_alloc_output, hwrm_ring_free_input,
hwrm_ring_free_output, hwrm_ring_grp_alloc_input,
hwrm_ring_grp_alloc_output, hwrm_ring_grp_free_input,
hwrm_ring_grp_free_output
