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

Replaced usage of void * with u64 in data structure shared between
brocade user space libraries and the bfa driver to address pointer
size changes across 32-bit vs 64-bit to have the compatibility between
32bit library and 64bit driver and vice versa.

D-Port is a new port type created with the intention of running link
level diagnostic tests like loopback, traffic test. In static D-port
mode, user configures the port to D-port mode and starts the test, but
in dynamic D-port, once the Brocade switch port is configured to
D-port, it will reject the regular FLOGI from HBA with reason that it is
in D-port mode. So based on the reason code HBA port will turn itself into
D-port and start diagnostic test.

- Introduced support for D-Port which is a new port mode during which
  link level diagnostics can be run.
- Provided mechanism to dynamically configure D-Port and initiate diagnostic
  tests to isolate any link level issues.
- In D-Port mode, the HBA port does not participate in fabric or login to the
  remote device or run data traffic.
- Diagnostic tests include running various loopback tests in conjunction with
  the attached device.

- Introduced rport qualifier structure and modified design to
  export remote ports with valid pid or valid pwwn to the user space.
- Introduced old_pid field in the rport structure and made changes to
  prevent re-creating a new remote port for an already existing rport
  that is transitioning to a delete state. (Happens if we receive a RSCN
  on the existing remote port that is getting deleted).
