[PATCH OLK-5.10 1/2] SCSI: spfc: remove SPFC driver

From: Yun Xu xuyun@ramaxel.com

Ramaxel inclusion category: bugfix bugzilla:https://gitee.com/openeuler/kernel/issues/I4ZR0O CVE: NA

There are some issues of the driver that cannot be fixed now. The driver is not good enough for the LTS quality requirements of openEuler，so remove it.
