[ck] Add myself as SSSRAID's maintainer

Hi All, I'm Steven Song from 3snic.com. https://www.3snic.com/ 3SNIC developed SSSRAID - 3SNIC SCSI RAID Controller driver, which is merged into OpenEuler and released with OpenEuler 22.03 SP2. I'm the maintainer of SSSRAID module in OpenEuler and hope I could get an opportunity to contribute SSSRAID to Anolis community too. . The list of files/directories I want to maintain is as follows: Documentation/scsi/sssraid.rst drivers/scsi/sssraid/ [1] https://gitee.com/openeuler/kernel/pulls/336 [2] https://gitee.com/openeuler/kernel/pulls/426 [3] https://gitee.com/openeuler/kernel/pulls/508 [4] https://gitee.com/openeuler/kernel/pulls/608 [5] https://gitee.com/openeuler/kernel/pulls/799 Thanks Steven Song
