net/qede/base: add APIs for dscp priority map configuration

Browse Source 
Add APIs for dscp priority map configuration. APIs added are
ecore_dcbx_get_dscp_priority(), ecore_dcbx_set_dscp_priority().
These base driver APIs can be used for dscp-map query/config.

Configure the doorbell queue (DORQ) to use vlan-id/priority.
