FogBugz #161193: Enhancing "bridge_enable_handoff" command
Bridge_enable_handoff command is used to enable all the bridges
based on handoff values. It took place after the FPGA programming.
This enhancement will remove all memory display commands as
they will trigger data abort if user press enter many times
after run bridge_enable_handoff.
The data abort is caused by U-Boot memory display features which
will auto increment the address after user press enter later on.
When this happen, the memory display command will display next
address which are not a valid address and causing data abort.
