net/bnxt: support two table scopes

Adding support for two table scopes. One for Exact Match tables
and other for External Exact Match tables.
New API to map a PARIF to an EEM table scope (set of Rx and Tx EEM
base addresses). It uses HWRM_TF_GLOBAL_CFG_SET HWRM to configure.
PARIF is handler to a partition of the physical port.
Adjustments to tf_global_cfg_set() to reduce overhead and nominal
name clarification.
