sata_highbank: Rename proc_name to the module name

commit 2cc1144a31f76d4a9fb48bec5d6ba1359f980813 upstream.

mkinitrd looks at /sys/class/scsi_host/host$hostnum/proc_name to find
the module name of a disk driver. Current name is "highbank-ahci" but
the module is "sata_highbank". Rename it to match the module name.
