bnxt_en: Restructure context memory data structures

The current code uses a flat bnxt_ctx_mem_info structure to store 8
types of context memory for the NIC.  All the context memory types
are very similar and have similar parameters.  They can all share a
common structure to improve the organization.  Also, new firmware
interface will provide a new API to retrieve each type of context
memory by calling the API repeatedly.

This patch reorganizes the bnxt_ctx_mem_info structure to fit better
with the new firmware interface.  It will also work with the legacy
firmware interface.  The flat fields in bnxt_ctx_mem_info are replaced
by the bnxt_ctx_mem_type array.  The bnxt_mem_init array info will no
longer be needed.
