net/mlx5e: Support PSP offload functionality

Add PSP offload related structs, layouts, and enumerations. Implement
.set_config and .rx_spi_alloc PSP device operations. Driver does not
need to make use of the .set_config operation. Stub .assoc_add and
.assoc_del PSP operations.

Introduce the MLX5_EN_PSP configuration option for enabling PSP offload
support on mlx5 devices.
