Jan Sokolowski 753b19afb1 IB/hfi1: Check eeprom config partition validity
Relying on a trailing magic value is incorrect. There are instances where
this is not present as trailing magic value has a specific purpose which is
not partition validation. Instead use the header magic value which is
present in all variants of the platform configuration and is intended for
validation. This is also used in other locations in the driver.

Jan Sokolowski bc5214ee29 IB/hfi1: Handle missing magic values in config file
Driver does not check whether proper configuration file exist in EPROM,
and treats empty partition as possible valid configuration, preventing
fallback to default firmware. Change EPROM read function to treat
missing magic number as read error.

Dean Luick e2113752b7 IB/hfi1: Restore EPROM read ability
Partially revert commit d079031742 ("IB/hfi1: Remove
EPROM functionality from data device"), bringing back
the ability to read from the EPROM.

This code will be used for driver-only acccess to the EPROM, hence
change EPROM read to save to a buffer instead of copy touser. Also
allow any offset and remove missed includes and leftover declarations.

Dennis Dalessandro f48ad614c1 IB/hfi1: Move driver out of staging
The TODO list for the hfi1 driver was completed during 4.6. In addition
other objections raised (which are far beyond what was in the TODO list)
have been addressed as well. It is now time to remove the driver from
staging and into the drivers/infiniband sub-tree.
