Discovery relates changes:
- Separated VPI_REGISTERED state of physical port into VFI_REGISTERED and
  VPI_REGISTERED state so that driver can unregister physical port VPI
  independent of VFI.
- Add code to unregister, re-init and re-register physical port VPI
  when physical port NportID change.
- Add code to unregister and re-register VPI of a vport when its Nport
  ID change.
- Add code in FDISC completion path to re-start FLOGI discovery when
  a FDISC complete with LOGIN_REQUIRED reason code.
- Fix a memory leak in lpfc_init_vpi_cmpl
- Add code to start a timer for vport to retry FDISC when CVL is received
  by a vport or physical port. If all Nports receive CVLs, then all timers
  are cancelled and a logical link level discovery will be started after
  one second.
- Flush ELS commands after killing all delayed ELS commands.

Added new callbacks phy_enable and set_phy_speed in the
mpt2sas_transport_functions template. This will allow end user to
enable/disable phys and change links rates using the SysFS interface.
Current implementation only supports direct attached phys, but we
could in the future add support for expander based phys.
A new subroutine mpt2sas_config_set_sas_iounit_pg1 was added;
this wrapper function used to send request to controller firmware to modify
the phys and link rates. A new subroutine _transport_find_local_phy was added;
a function for easly obtaining the local phy object for direct attached.

Example to disable a phy
echo 0 > /sys/class/phy3:0/enable

Example to enable the same phy
echo 1 > /sys/class/phy3:0/enable

Example to change the link rate to 1.5
#echo "1.5 Gbit" > /sys/class/phy3:0/maximum_linkrate
#cat /sys/class/phy3:0/negotiated_linkrate
1.5 Gbit

Example to change the link rate to 3.0
#echo "3.0 Gbit" > /sys/class/phy3:0/maximum_linkrate
#cat /sys/class/phy3:0/negotiated_linkrate
3.0 Gbit

Example to change the link rate to 6.0
#echo "6.0 Gbit" > /sys/class/phy3:0/maximum_linkrate
#cat /sys/class/phy3:0/negotiated_linkrate
6.0 Gbit

On ppc64, an 32bit application was failing due to data buffers not being
