net/bnxt: add 64B SRAM record management with RM

HCAPI RM now manages 64Byte records instead of 8Byte.
Truflow core RM will manage the same. The tf_tbl core
APIs now return 8B pointer addresses. These can
be used directly as SRAM pointers in Action Records.
When communicating with the firmware 8 byte addresses
will be used.
