[PATCH 3/5] regex/mlx5: remove useless constants

[Thomas Monjalon]

All these constants were unused since their introduction:

- MLX5_REGEX_WQE_CTRL_OFFSET
- MLX5_REGEX_RXP_ROF2_LINE_LEN
- MLX5_RXP_BF4_ROF_VERSION_STRING
- MLX5_RXP_CTRL_TYPE_*
- MLX5_RXP_CTRL_JOB_DESC_FLAGS
- MLX5_RXP_CTRL_VALID
- MLX5_RXP_INITIALIZATION_TIMEOUT

This constant became unused after supporting combined rule file:

- MLX5_RXP_POLL_CSR_FOR_VALUE_TIMEOUT

All these constants became unused after removing DB and register R/W:

- MLX5_RXP_MAX_ENGINES
- MLX5_RXP_EM_COUNT
- MLX5_RXP_DB_NOT_ASSIGNED
- MLX5_RXP_CSR_NUM_ENTRIES
- MLX5_RXP_CSR_CTRL_DISABLE_L2C

Fixes: 4d4e245ad637 ("regex/mlx5: support enqueue")
Fixes: f324162e8e77 ("regex/mlx5: support combined rule file")
Fixes: ab74680160ba ("regex/mlx5: support combined ROF file")
Fixes: b34d816363b5 ("regex/mlx5: support rules import")
Fixes: ab2e0b0d3531 ("regex/mlx5: remove register read/write")
Fixes: 9fa82d287f65 ("regex/mlx5: move RXP to CrSpace")
