bnxt_en: Allocate backing store memory for FW trace logs

Allocate the new FW trace log backing store context memory types
if they are supported by the FW.  FW debug logs are DMA'ed to the host
backing store memory when the on-chip buffers are full.  If host
memory cannot be allocated for these memory types, the driver
will not abort.
