ilo: replace domains by reloc flags

It is simpler and is supported by the kernel.  It cannot be used with
libdrm_intel yet though.
ilo: remove max_batch_size

It is used to derive an artificial limit on max relocs per bo.  We choose not
to export it anymore.
ilo: rename intel_bo_map_unsynchronized()

Rename it to intel_bo_map_gtt_async().
ilo: use genhw command opcodes

Replace ILO_GPE_MI and ILO_GPE_CMD with magic values by descriptive genhw
macros.
