net: dcb: add helper functions to retrieve PCP and DSCP rewrite maps
Add two new helper functions to retrieve a mapping of priority to PCP
and DSCP bitmasks, where each bitmap contains ones in positions that
match a rewrite entry.
dcb_ieee_getrewr_prio_dscp_mask_map() reuses the dcb_ieee_app_prio_map,
as this struct is already used for a similar mapping in the app table.
