define generation repeated defines

[markuslsra]

Defines for repeated registerfiles should be one define and not many...

Example:

Now:

`define RFS_LANE_0_RF_AWIDTH 5
`define RFS_LANE_0_RF_RWIDTH 44
`define RFS_LANE_0_RF_WWIDTH 44

`define RFS_LANE_1_RF_AWIDTH 5
`define RFS_LANE_1_RF_RWIDTH 44
`define RFS_LANE_1_RF_WWIDTH 44

Should be:

`define RFS_LANE_RF_AWIDTH 5
`define RFS_LANE_RF_RWIDTH 44
`define RFS_LANE_RF_WWIDTH 44
