iommu-helper: use bitmap library
Use bitmap library and kill some unused iommu helper functions.
1. s/iommu_area_free/bitmap_clear/
2. s/iommu_area_reserve/bitmap_set/
3. Use bitmap_find_next_zero_area instead of find_next_zero_area
This cannot be simple substitution because find_next_zero_area
doesn't check the last bit of the limit in bitmap
4. Remove iommu_area_free, iommu_area_reserve, and find_next_zero_area
