staging/rdma/hfi1: Adjust EPROM partitions, add EPROM commands

Browse Source 
Add a new EPROM partition, adjusting partition placement.

Add EPROM range commands as a supserset of the partition
commands.  Remove old partition commands.

Enhance EPROM erase, creating a range function and using the
largest erase (sub) commands when possible.
