Vijaya Mohan Guvva 079bcbc35c [SCSI] bfa: fru vpd date update changes 
1. While FRU VPD data update, inform firmware to send a completion event
   on I2C bus. Without this change, firmware used to send completion
   message on I2C bus for every chunk of FRU VPD update.
2. Support for FRU VPN update on CHINOOK2 cards.
3. Append port count to the model name to differentiate between single
   port and dual port model of 1860.
4. Update the size of the model name to 16bytes
