mlx4_core: Support multiple pre-reserved QP regions
For ethernet support, we need to reserve QPs for the ethernet and
fibre channel driver. The QPs are reserved at the end of the QP
table. (This way we assure that they are aligned to their size)
We need to consider these reserved ranges in bitmap creation, so we
extend the mlx4 bitmap utility functions to allow reserved ranges at
both the bottom and the top of the range.
