[ECP5UM WORKAROUND] The PCS' lsm_status signal is not asserting

Modify the rdo_rx_pcs_rst_c logic based on the RSL documentation.
1. Open the *_softlogic.v, look for the rdo_rx_pcs_rst_c. Add the input for the OR logic such as rdi_rx_los_low_s, rdi_rx_cdr_lol_s and rui_rx_pcs_rst_c. 
2. Open the IP RTL wrapper.Look for *_FFC_LANE_RX_RST for the appropriate channel#. Replace the logic to add other reset inputs.


3. Insert the COMMA to initiate synchronization on the channel.
This is stated at section 8.2.1 of ECP5 SerDes/PCS TechNote.


ROOT CAUSE of LSM_STATUS_S being LOW: Invalid RSL logic on rdo_rx_pcs_rst_c reset output and need to send proper COMMA to allow synchronization of the serial data.
