md: raid0 :Enables chunk size other than powers of 2.
Maintain two flows, one for pow2 chunk sizes (which uses masks and
shift), and a flow for the general case (which uses sector_div).
This is for the sake of performance.
- introduce map_sector and is_io_in_chunk_boundary to encapsulate
those two flows better for raid0_make_request
- fix blk_mergeable to support the two flows.
