[PATCH 3/6] PS3: gelic: code cleanup

PS3: gelic: code cleanup

Code cleanup:
 - Use appropriate prefixes of names instead of fixed 'gelic_net'
   so that objects of the functions, variables and constants can be esitimate.
 - Remove definitions for IPSec offload of the gelic hardware.  This
   functionality is never supported in PS3.
 - Group constatns with enum.
 - Use bitwise constatns for interrupt status, instead of bit number to
   eliminate shift operations.
 - Style fixes.
