Update the PMD to use the 1.5.1 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 updated:
hwrm_stat_ctx_alloc_input, hwrm_stat_ctx_alloc_output,
hwrm_stat_ctx_free_input, hwrm_stat_ctx_free_output,
hwrm_stat_ctx_clr_stats_input, hwrm_stat_ctx_clr_stats_output,
hwrm_exec_fwd_resp_input, hwrm_exec_fwd_resp_output
