MLK-24934 mic: imx-host: fix kernel panic when cat /sys/class/mic/mic0/family&stepping
Since we didn't implement the family and stepping function callbacks for
cosm_hw_op, when cat /sys/class/mic/mic0/family and
/sys/class/mic/mic0/stepping at userspace will cause kernel panic:
root@imx8qmmek:~# cat /sys/class/mic/mic0/family
[ 44.736286] Unable to handle kernel NULL pointer dereference at
virtual address 0000000000000000
root@imx8qmmek:~# cat /sys/class/mic/mic0/stepping
[ 66.614414] Unable to handle kernel NULL pointer dereference at
virtual address 0000000000000000
So add family and stepping callbacks to avoid kernel panic.
