Cleanup around handling of feature bits:
- address word/dword/qword confusion
- simplify interfaces so callers do not need to
  remember in which 64 bit chunk each bit belongs

changes from v4: address comments by Jason
  move features variable to beginning of block
  unsigned long -> u64 - they are not the same
changes from v3:
  drop an out of date unnecessary kdoc parser change

changes from v2:
- drop unnecessary casts
- rework the interface to use array of bits not

  virtio: clean up features qword/dword terms
  vhost: switch to arrays of feature bits
