4.3.1.5. set_hssi_profile for F-Tile

This SAL command is used to program the profile information to the DR CSR registers and set the Trigger Reconfig bit to start the DR sequence. The DR completion status is reflected in HSSI Command/Status CSR bit [3:2] with error indication shown in bit 4. This set_hssi_profile SAL command is executed in HW and not through SAL NIOS firmware to avoid extra latency introduced in the DR sequence.
