Ramaxel inclusion
category: features
bugzilla: https://gitee.com/openeuler/kernel/issues/I4JXCG
CVE: NA

Changes:
1. Use bsg module to replace with ioctrl
2. Split scmd_tmout_nonpt into two parameters:
   scmd_tmout_vd/scmd_tmout_rawdisk
3. Return -ETIME instead of -EINVAL when command is timeout.
4. Add one module parameters: max_io_force.
5. Remove some unnecessary module parameters.
6. Report disks by the order of channel/target id.
7. Add host_reset handler.
8. Use get_unaligned_be24.
