From: Sucharitha Sarananaga <ssaranan...@marvell.com>
This patch introduces a new API to get AE EC group table
address and added static_assert checks to ensure that each
enum value in roc_ae_ec_id matches its expected constant.
This helps catch accidental changes or reordering of enum
values at compile time.
