IB/ehca: Remove use of do_mmap()

Browse Source 
This patch removes do_mmap() from ehca:
 - Call remap_pfn_range() for hardware register block
 - Use vm_insert_page() to register memory allocated for completion
   queues and queue pairs
 - The actual mmap() call/trigger is now controlled by user space,
   ie. libehca
